Description

Cross flow confluence, which is drawn, rushes self collapsing levee dam geotechnique's plate very floodway

Technical field

The invention belongs to dykes and dams very flood diversion hydraulic engineering technical fields, also belong to the defense technology field that reply water is attacked, More particularly to the design method on self collapsing levee dam, geotechnological plate very floodway.

Background technique

Japanese 75 western Japan heavy rains in 2018, Cangfu city very breach a dyke for one river of raised path between farm fields, and flood destroys by rush of water about three/ One house forces thousands of people to climb onto the roof emergency, only very for raised path between farm fields, is resulting at least 28 people wrecked, Japanese authorities the force of rain most When serious, went out evacuation command to 5,000,000 human hairs, but these order many common people not take seriously, not due to flood Certainty, the uncertainty to inrush, theoretical under technical conditions in existing flood control, " wolf is coming " is global social concern. Japan's No. 10 typhoon " Lion Rock " heavy rain in 2016 causes Hokkaido, Japans and the Northeast more people of waterflooding of breaching a dyke wrecked.Japan On September 11 days 10,2015 successive two this generation of river floods overflow dike and burst, and cause the more people of 7 personnel deaths missing and injury, Fortune is caused to lose, 20 centimetres of dykes and dams that 10 years one 4 meters high for meeting standard of flood are crossed after eagre inrush, people The Japan mouthful more, national territorial area is small, economically developed inrushes disaster by super standard flood year after year, once the people that inrushes of happening suddenly has little time Escape, this is global problem.According to Chinese floods and droughts bulletin: 12 years to 14 years water conservancy projects damaged or destroyed by flood years lost 46,800,000,000 yuan extremely 44600000000 yuan, national water engineering facility damaged or destroyed by flood in 16 years is at totally 17.57 ten thousand, and 697.7 hundred million yuan of water conservancy projects direct losses, wherein greatly Medium-sized reservoir 111, small reservoir 2337, at dyke 66950, dyke 90250,14256, sluice, irrigating facility At 233879.A large amount of frequent damaged or destroyed by flood reservation or revocation of the low mini engineering of standard of flood are problems, because mini engineering, which has, meets national conditions Particular advantages, built just to have its existent value by taking small reservoir as an example, in plato and hill, they are decentralized, access on the spot Water floods that the small, effect on environment in arable land is small to require that low, damaged or destroyed by flood consequence is small without land occupation water supply project over long distances, management, it meets Chinese people is ploughed few national conditions more, this problem is all not present in US and Russia Europe；Medium and small reservoirs by water attack threaten it is small, if central water supply Large reservoir encounter war water and attack threat, not water storage grain security is compromised, and it is to threaten that water storage water, which attacks dam break, because of west state Family, which attacks water, is classified as war important option, and water attacks dam break and destroys lower reservoir dam, chain destruction dyke, flood-diversion sluice, head works work Journey leads to river diversion, and there are more than 80,000 reservoirs and numerous high dykes, flood-diversion sluice, head-work in China, and it is difficult for how coping with water and attacking Topic is also blank spot.In addition, Rapid-Urbanization, remote water project management shortage of staff is problem, national boundary river trans-boundary water point Flood, do not have build detention basin medium or smallsized river how flood diversion, divide sluice management and maintenance maintenance, the single flood releasing structure of reservoir Contingency is problem；The plastic garbages such as medical treatment, old chemical fibre clothes recycling are problems.

If being to solve numerous low water head water conservancy projects using emerging et al. the self collapsing levee dam geosynthetics very floodway of leaf A kind of feasible scheme of economic technology of building damaged or destroyed by flood.Due to there is no self collapsing levee dam design theory, become the barrier of popularization and application Hinder.Self collapsing levee dam is ancient in China and has it, and ancient times Dujiang weir just uses blown sand weir, just bursts as Japanese dyke overflows 20 centimetres of water Case can be found everywhere, this illustrates that self collapsing levee dam has feasibility, but also having self collapsing levee dam not burst in time causes key dam to overflow dam Case, furnish a huge amount of money for since the fifties to carry out the self collapsing levee dam design reason that experimental study is not built consensus both at home and abroad By it becomes 60 years pendent worldwide theoretical puzzles.Self bursting dam is introduced into Design of Reservoirs in modern American people, Nineteen fifty-nine E.RoyTinney introduces prototype and model investigation, opens self bursting dam system in " performance of flushing from weir of bursting " text Journal of Sex Research of uniting draws immediately because self bursting dam super standard flood enabling probability is small, low cost, automatic opening, advantage convenient for management Countries in the world are played to furnish a huge amount of money for carry out follow-up research.The F Sai Tuerke of Turkey in 1978 is in " a kind of novel spillway " Point out " hard surface anti-impact makes self bursting dam be difficult to the problem of bursting, and solves using jet-bedding is drawn ".Zhang Kejian is in " Zhejiang reservoir spillway Building overview and related knowledge question of water conservancy " in point out that " after 75.8 flood of Henan China, planning and design institute of Ministry of Water Resources and Power Industry organizes river South, Liaoning, Zhejiang, Anhui etc. save the experimental study that self bursting dam is carried out in relation to design R&D institution, live prototype or large scale Not only model test cost is very big, and the dam body that testing data also can only explain under this kind of dam type and this kind of experimental condition washes away Situation, can not design to provide for self bursting dam generally can provide the analysis calculation method of application and just once occur in small-sized hilly pond reservoir Cross and do not cause inundating the dam by flood because the temporary adhesive low bank of earth between fields is not destroyed by rush of water in time ", the emphasis of China's research is also to draw jet-bedding and draw washing pipe, The disadvantage is that testing expenses are high and draw jet-bedding scale, the design of spacing needs test determination, can not be protected in face of uncertain flood Card draws routed in time, and drawing jet-bedding maintenance management is also problem." Hydroplus-one kind is novel recommending Swedish patent by Guo Jun Flood control water blocking formula from burst weir " in quote inventor " the long-term consolidation of self bursting dam is allowed to be difficult in flood period by the problem of destroying by rush of water ", Consolidated clay is solved the problems, such as using the concrete cut to topple automatically, because can precisely quantify the condition of bursting, more than ten of state Family uses.But its dissipation and scouring requires height, cost high and topples to will cause disaster of surging greatly very much from bursting.Pang Min " is bursting certainly The design of formula emergency spillway " point out " geomembrane self collapsing levee dam breaking is fast ", it can protect to stay without reference to geomembrane and swim dam body resistance Stagnant the problem of washing away." Chinese rivers flood control book series-Haihe River volume " Haihe River uses self collapsing levee dam, exists because self collapsing levee is anti-and is unable to control The shortcomings that, using human-generated explosives as alternative.There is presently no the design theories that self collapsing levee is prevented, generally general is human-generated explosives Flood diversion method, advantage can overcome consolidated clay, hard surface uncertain, the management of disadvantage flood season and explosive management require it is high, Once explosion flood diversion is out of control.Dykes and dams burst very generally, without the feasible self collapsing levee dam design theory with common recognition, just without complete skill Art, the reason of be that present self bursting dam design theory is to quantify to reach standard of flood as defined in specification, i.e. self bursting dam starts to open Move that reservoir level rises to the time of normal water level and self bursting dam time of bursting coincide, and various dams are from bursting phenomenon mechanism all very Complexity can be solved without mathematical model at present；At present by research technique, only draw jet-bedding self bursting dam it is big have than ruler bulk testing it is similar Property, the statically indeterminate structure for drawing three face consolidated clays of jet-bedding complicates the issue, while test can't resolve the uncertain of flood Property, unlimitedness and consolidated clay and hard surface cause from the uncertain problem burst, it is all at present by experimental design Self bursting dam must be rare singularity lanthanon, be hardly obtained the verifying of practice；It is limited by economic technology condition a large amount of middle-size and small-size Dam, head-work, dyke, canal structure, cofferdam, specification allows super standard flood damaged or destroyed by flood, although the damaged or destroyed by flood of magnanimity, specification People are allowed to be accustomed to.

Super standard flood of the invention further includes flood caused by attacking more than administrative standard and war water, flood diversion of the invention Road includes reservoir spillway, emergency spillway, head works floodway and dyke floodway, and dykes and dams include reservoir dam and river and lake dike Anti-, geosynthetics adds colour bar cloth including geotechnological plate, composite geo-membrane, waterproof geotechnological woven fabric, colour bar cloth, non-woven fabrics, soil Work plate includes conventional geotechnological plate, bamboo wound composite plate, and geotechnological plate film cloth is knitted including geotechnological plate, geomembrane, waterproof geotechnique Cloth.

In conclusion establish self collapsing levee dam design theory and complete set technology to be related to Homeland Security in the urgent need to address Theoretical and technical problem；It is Hydraulic Engineering Design under the conditions of urbanization, mechanization, management theory and technology in the urgent need to address Problem；It is boundary river between country, the flood diversion of across footpath river theory and technical problem in the urgent need to address.

Utilize the method and Zhe Sheng in 1978 of leaf emerging et al. rock-fill dams damaged or destroyed by flood mathematical model and the evolution of origin cause of formation Dynamic Coupling Water conservancy and hydropower Science Institute etc. " report of South Mountain reservoir self bursting dam experimental stage " data establishes dykes and dams and bursts mechanism, recycles The dykes and dams of Ye Xing are prevented and reduced natural disasters the method for design theory, are established self collapsing levee dam and are prevented and reduced natural disasters design theory and complete set technology, for solution Certainly pendent global problem provides a kind of method.

Unrestrained water dykes and dams burst be broken to because coupling destroy dynamical evolution, be typical case, cross flow dykes and dams downstream with unrestrained water Clay Microstructure It is open channel uniform flow erosion damage that erosion damage, which takes place, in slope, is that unrestrained water dykes and dams downstream sandy soil slope headcut scour destroys at this time Stage beginning, corresponding weir headwater depth are that critical dykes and dams headcut scour destroys weir headwater depth H_d；Washing away makes dam base dam slope steepening, Open channel nonuniform flow precipitation fluidised form level erosion damage step by step is formed, the higher level of tracing to the source of dykes and dams washes away faster, unrestrained water dykes and dams bottom After portion's gradient is greater than sandy soil internal friction angle, it is broken that sand earth embankment dam body generates the straight line landslide that inclination angle is sandy soil internal friction angle Bad, dykes and dams slope surface is transferred, and turning point is occurred in dykes and dams slope surface and is developed into down stream erosion damage, and the higher down stream of dykes and dams is traced to the source punching It brushes faster；When slope straight line landslide in unrestrained water dykes and dams downstream extends under the road surface of dykes and dams top, hard surface forms cantilever down stream, in dam abutment Place forms road surface down stream erosion damage, and the cantilever road surface on scour hard surface basis, Clay Microstructure downstream is used in self weight, water recast Lower generation moment of flexure stress rupture and local shedding develop as Clay Microstructure cantilever down stream, lose sandy soil after dykes and dams Clay Microstructure Dyke (dam) support, the Circular Slip peeled off layer by layer is generated under osmotic pressure, Gravitative Loads and is destroyed, and washing away, landslide coupling is broken Under bad, cross flow dykes and dams Clay Microstructure is thinning and seepage erosion occurs, and empties roadbed, and hard surface is washed away in self weight, water weight, dynamic water Effect is lower to occur fall damage, is unrestrained water dykes and dams crevasse initial phase at this time；When unrestrained water dykes and dams Clay Microstructure top loses hardening road When the scour protection of face, overflows water dykes and dams Clay Microstructure and incision erosion damage occurs, under unsaturation consolidated clay anti-impact flow velocity in top is big It cuts slowly, seepage flow saturation consolidated clay anti-impact flow velocity in bottom is small and the big incision of flow velocity is fast, and Clay Microstructure is in self weight, water pressure, soil pressure The stress rupture that unrestrained water dykes and dams Clay Microstructure cantilever occurs fracture or topples under power effect, the cohesion of top unsaturation consolidated clay Power, internal friction angle are big, and tension stress is big, and generation stress rupture is slow, and bottom unsaturation consolidated clay cohesiveness, internal friction angle are small, Tension stress is small, and generation stress rupture is fast, and the crevasse depth of water increases, the quick incision erosion damage of crevasse Clay Microstructure, is just formed unrestrained Water dykes and dams burst the stage, under the conditions of critical dykes and dams headcut scour destroys weir headwater depth, overflow water dykes and dams crevasse initial phase evolution It is a slow process, it is more lower slower overflows water dykes and dams；In dykes and dams weir headwater depth on critical dykes and dams top incision erosion damage weir Depth of water H_uUnder the conditions of, dykes and dams top downstream road surface occur to destroy first and on prolong, unrestrained water dykes and dams Clay Microstructure loses scour protection hair It gives birth to and cuts erosion damage, unrestrained water dykes and dams crevasse initial phase is formed, while downstream slope occurs headcut scour and destroys, with regard to quick evolution Burst the stage for unrestrained water dykes and dams；When dykes and dams weir, headwater depth reaches critical not erosion damage weir headwater depth H_n, dykes and dams crevasse lateral incision is slow Slowly, the unrestrained water dykes and dams crevasse stabilization sub stage is formed；The relatively narrow jet-bedding formula self collapsing levee dam that draws is the affixed statically indeterminate structure in three faces, and top is non- Cohesiveness, the internal friction angle for being saturated consolidated clay are larger, fracture, the stress rupture that topples it is slow, bottom saturation consolidated clay Cohesiveness, internal friction angle it is smaller, fracture, the stress rupture that topples it is fast.

Unrestrained water dykes and dams burst be broken to because coupling destroy dynamical evolution, be typical case, cross flow dykes and dams with unrestrained water Clay Microstructure It is open channel uniform flow erosion damage that erosion damage, which takes place, in downstream slope, is that unrestrained water dykes and dams downstream sandy soil slope headcut scour is broken at this time Bad initial phase, corresponding weir headwater depth are that critical dykes and dams headcut scour destroys weir headwater depth H_d；Washing away makes dam base dam slope Steepening, forming open channel nonuniform flow, precipitation fluidised form level erosion damage, the higher level of tracing to the source of dykes and dams wash away faster, Man Shuidi step by step After dam bottom slope is greater than sandy soil internal friction angle, sand earth embankment dam body generates the straight line that inclination angle is sandy soil internal friction angle and comes down It destroys, dykes and dams slope surface transfers, turning point occurs in dykes and dams slope surface and develop into down stream erosion damage, the higher down stream of dykes and dams is traced to the source It washes away faster；When slope straight line landslide in unrestrained water dykes and dams downstream extends under the road surface of dykes and dams top, hard surface forms cantilever down stream, on dam Down stream erosion damage in road surface is formed at shoulder, scour hard surface basis, the cantilever road surface in Clay Microstructure downstream is in self weight, water recast The local shedding with lower generation moment of flexure stress rupture develops as Clay Microstructure cantilever down stream, loses sand after dykes and dams Clay Microstructure The support of earth embankment dam body generates the Circular Slip peeled off layer by layer under osmotic pressure, Gravitative Loads and destroys, and is washing away landslide coupling Under destruction, cross flow dykes and dams Clay Microstructure is thinning and seepage erosion occurs, and empties roadbed, hard surface is in self weight, water weight, dynamic water punching Brush effect is lower to occur fall damage, is unrestrained water dykes and dams crevasse initial phase at this time；When unrestrained water dykes and dams Clay Microstructure top loses hardening When the scour protection of road surface, overflows water dykes and dams Clay Microstructure and incision erosion damage occurs, unsaturation consolidated clay anti-impact flow velocity in top is big Incision is slow, and seepage flow saturation consolidated clay anti-impact flow velocity in bottom is small and the big incision of flow velocity is fast, and Clay Microstructure is in self weight, water pressure, soil The stress rupture that unrestrained water dykes and dams Clay Microstructure cantilever occurs fracture or topples under pressure effect, the cohesion of top unsaturation consolidated clay Power, internal friction angle are big, and tension stress is big, and generation stress rupture is slow, and bottom unsaturation consolidated clay cohesiveness, internal friction angle are small, Tension stress is small, and generation stress rupture is fast, and the crevasse depth of water increases, the quick incision erosion damage of crevasse Clay Microstructure, is just formed unrestrained Water dykes and dams burst the stage, under the conditions of critical dykes and dams headcut scour destroys weir headwater depth, overflow water dykes and dams crevasse initial phase evolution It is a slow process, it is more lower slower overflows water dykes and dams；In dykes and dams weir headwater depth on critical dykes and dams top incision erosion damage weir Depth of water H_uUnder the conditions of, dykes and dams top downstream road surface occur to destroy first and on prolong, unrestrained water dykes and dams Clay Microstructure loses scour protection hair It gives birth to and cuts erosion damage, unrestrained water dykes and dams crevasse initial phase is formed, while downstream slope occurs headcut scour and destroys, with regard to quick evolution Burst the stage for unrestrained water dykes and dams；When dykes and dams weir, headwater depth reaches critical not erosion damage weir headwater depth H_n, dykes and dams crevasse lateral incision is slow Slowly, the unrestrained water dykes and dams crevasse stabilization sub stage is formed；The relatively narrow jet-bedding formula self collapsing levee dam that draws is the affixed statically indeterminate structure in three faces, and top is non- Cohesiveness, the internal friction angle for being saturated consolidated clay are larger, fracture, the stress rupture that topples it is slow, bottom saturation consolidated clay Cohesiveness, internal friction angle it is smaller, fracture, the stress rupture that topples it is fast；The cross flow confluence

automatic controllable flood diversion economical, technically feasible；Because have determining flood diversion place, really Fixed flood diversion water level is aided with automatic forecasting system again, and resident, peasant understand autonomous organizations prevention, withdraw automatically, government organization flood control, It withdraws and is also easy, it solves the global social problem of " wolf is coming ".5. cross flow confluence of the invention, which is drawn, rushes self collapsing levee dam: with The fundamental difference on existing self collapsing levee dam is that (1) changes existing clay core body self collapsing levee dam according to self collapsing levee dam breaking mechanism Structure, construct set of cheap, structure it is simple, it is super let out it is super it is routed subtract the cross flow confluence surged and draw rush self collapsing levee dam, according to certainly Inrush dam breaking mechanism, to it is set of it is super let out it is super it is routed subtract the cross flow confluence surged and draw rush that self collapsing levee dam carries out subregion and quantization is set Meter, probabilistic, unlimited super standard flood problem and uncontrollable disaster of surging can not be solved by solving existing self collapsing levee dam Problem, solve the insurmountable consolidated clay in existing self collapsing levee dam, hard surface, coarse grain diameter sandstone dam body from burst uncertainty Problem, solve the problems, such as that the design of existing self bursting dam can not be general using individual test；(2) cross flow confluence, which is drawn, rushes self collapsing levee Dam subregion effect is prolonged on female easy sand surfing stone earth embankment dam body area headcut scour of non-sticky destroys and straight line comes down, and causes parting hard Change road surface quickly collapses, impervious body loses dyke (dam) support and overturning, and then causes the easy sand surfing stone earth embankment dam of sub- non-sticky Seepage erosion；The sub- easy sand surfing stone earth embankment dam of non-sticky, seepage flow further causes hard surface collapsing, in low water head, low flow velocity item Seepage flow quickly bursts with washing away under coupling under part, and self collapsing levee dam obtains enough flow velocity realizations and draws punching, coarse grain diameter or containing gluing Property soil dyke (dam), also slow down dam break using slow burst while reducing cost using natural material and surge disaster；Consolidated clay is anti- Body is seeped, guarantees that safety under conditions of bursting, is burst slowly using consolidated clay and slows down dam break and surge in incision flow velocity；(3) draw soil of blurting out Work plate film cloth antiseepage curtain body replaces drawing the problem of clay cut-off wall of blurting out avoids consolidated clay cut-pff wall, easily rushes in sub- non-sticky The destruction of sandstone earth embankment dam headcut scour, which is toppled, to fall off, and then the destruction of small dike dam, hard surface collapsing is caused to burst and draw punching, it is solution The key for the problem for certainly having the low cross flow head of hard surface, short self collapsing levee dam breaking slow；(4) confluence draws punching with lesser cross flow Head acquisition is biggish to wash away discharge per unit width, and cross flow, which has to surpass, lets out ability, and cross flow head bursts more greatly faster, has super routed energy Power, it solves the problems, such as to solve super standard flood uncertainty, unlimitedness；On the one hand, self collapsing levee dam draws subregion of blurting out, and is converging Scour causes to prolong on the easy sand surfing stone earth embankment dam area straight line landslide of female non-sticky, and naughty sky draws the curb stone foundation blurted out, and causes curb Stone collapses, and further increases and washes away head, and kerbstone, which plays, laterally concentrates guide functions, after so that the road surface for having transverse joint is collapsed upwards Trip extension；On the other hand, wider to draw after easily routed geotechnological plate film cloth antiseepage curtain body of blurting out draws and blurt out and quickly burst, it is risen in kerbstone To guide functions, basis under lateral scour road surface are laterally concentrated, road bed collapses in the case where coupling is washed in a pan in downstream Hui Tao, side, The clay cantilever core-wall structure for losing the support of sandstone dyke (dam), loses the affixed effect of cantilever, makees in water pressure, soil pressure, seepage flow Overturning occurs with lower clay core body, solve three face consolidation statically indeterminate structure of top unsaturation consolidated clay low flow velocity, Anti-impact, tension are burst probabilistic problem under low head condition, and it is uncertain to solve hard surface, coarse grain diameter sandstone dam bursting The problem of property.Non-sticky easy sand surfing stone soil area is lacked for locality, subregion can be improved from routed speed and reduce project cost, Consolidated clay, coarse grain diameter sandstone dam body slow abatement of the bursting dam that inrushes surge.Using drawing the easy sand surfing stone of high, the female non-sticky of punching pin dykes and dams Earth embankment dam area internal friction angle, female sandstone dyke (dam) scour hole depth divide self collapsing levee dam subregion, Quantitative design self collapsing levee dam subregion.Road Kerb cross flow confluence, which is drawn, rushes self collapsing levee dam, and advantage is that project amount saves, the disadvantage is that parting hard surface slows down from speed of bursting；Upper alien Dike kerbstone cross flow confluence, which is drawn, rushes self collapsing levee dam, and advantage is that the small dike dam higher flow velocity that bursts of acquisition easily to burst washes away female dykes and dams Parting hard surface reduces influence of the mother stock seam hard surface to bursting, convenient for management, the disadvantage is that project amount is big compared with the former；Pipe Band draws with kerbstone cross flow confluence rushes self collapsing levee dam, and advantage is to work as to draw the washing pipe connection small flood of woven fabric band by pipe band flood diversion, no Start self collapsing levee dam, is directly unfolded into and draws washing pipe and draw punching, if there is accident in main body flood diversion building, active when can meet an urgent need Draw punching from flood diversion of bursting, great flood draws washing pipe and kerbstone cross flow confluence draws punching jointly, and disadvantage management requires high.The present invention with it is existing Cross flow self bursting dam compares, now only reservoir self bursting dam, the present invention cover reservoir dam and the various heads of river and lake canal dyke at Self collapsing levee dam structure is covered, it is not influenced by consolidated clay, hard surface；Compared with existing geomembrane self collapsing levee dam, present invention soil Work plate film cloth antiseepage curtain body prevents its retardance from routed problem, and its selection is extensively not limited to geomembrane；With automatically topple Concrete cut compares, low cost of the present invention, can gradual control surge, avoid disastrous toppling from surging；With human-generated explosives Flood diversion is compared, and the present invention is unattended, automatic controllable flood diversion, convenient for management；There is lock to draw jet-bedding with existing, draw washing pipe self collapsing levee dam Compare, wider cross flow confluence draws the easy cantilever design burst blurted out, the simple low cost of structure, and spacing pair of blurting out is drawn in encryption Cost influence is little, it solves the existing solid clay cut-off wall self collapsing levee dam in three faces for having lock to draw jet-bedding, drawing washing pipe and tries by individual The problem of Data Design is tested, it controls automatic flood diversion without gate.6. cross flow confluence of the invention, which is drawn, rushes self collapsing levee dam geotechnique's plate Unusual floodway: being with existing self collapsing levee dam floodway fundamental difference, according to self collapsing levee dam breaking mechanism, utilizes reason of preventing and reducing natural disasters By, carry out the height difference of self collapsing levee dam and non-overflow dykes and dams, multistage self collapsing levee dam it is differential be versatility Quantitative design, small water is small Routed, great flood is burst greatly, and realization is prevented and reduced natural disasters, it solves the unlimitedness, probabilistic problem of super standard flood, is solved a at present The problem of body experimental design multistage self bursting dam；Design theory of foundation very floodway super standard flood preventing and reducing natural disasters designs geotechnological plate Very floodway solves the problems, such as numerous small hydraulic project damaged or destroyed by floods and towards the flood diversion of beach field.The emerging multistage self collapsing levee dam with leaf Emergency spillway is compared, and Ye Xing only limits to low water head flood diversion towards beach field in pervious multistage self collapsing levee dam, and the present invention is on material It is widely applicable to expand to geotechnological plate, increases separation levee, slope connection in structure；Staggered floor advantage of the invention is structure and hydraulics Feature is simple, and disadvantage is not suitable for vehicle pass-through, is suitable for small dike's self collapsing levee dam, separation levee advantage is can temporarily to set up Simple bridge just In traffic and block diffluence pass, shunt elevation of weir crest can with flexible arrangement, by flood diversion elevation of weir crest can timely flood diversion, It flushes to have to surpass with ground and lets out ability and take into account water drainage, the disadvantage is that project amount is big, require height or control in time to divide suitable for traffic The dyke and reservoir of flood can quickly face especially in war and build suspension bridge and resume traffic with functions of national defense；Slope advantage is vehicle P Passable, the disadvantage is that complicated from routed hydraulic characteristic, from bursting, water level is difficult to accurate grading control, and it is demanding certainly to be suitable for traffic Inrush dam；It is that the shared small structure of dissipation and scouring section project amount is simple that advantage is expanded in side, the disadvantage is that flood diversion water level is single and higher The super ability of letting out in weir is small, once flood diversion blocks traffic, the dyke and small reservoir that have drainage gate of less demanding suitable for traffic；It is more Grade lamination advantage is that project amount is small, and flood diversion weir height is variable, and great flood divides greatly, small point of small flood, and structure is complicated and it is folded to require for disadvantage Layer height is larger, and suitable for higher self collapsing levee dam, traffic is of less demanding, dykes and dams of flood diversion limited width.With no emergency spillway Design of Reservoirs project plan comparison, the present invention can be to avoid the unexpected thing of the single earth and rockfill dam dam abutment spillway for having lock to control big aperture Therefore jeopardize the problem of earth dam safety, it avoids cost high and enables the extremely low steel construction of probability at full capacity and corrode to need to furnish a huge amount of money for conserve The problem of maintenance, avoid outdoor concrete by aging, freeze thawing, frost heave, sedimentation, seepage erosion problem；Compared with flood-diversion sluice, this There is no gate corrosion, outdoor concrete aging, freeze thawing, frost heave and routine servicing maintenance and problem of management, automatic flood diversion for invention Administrative vulnerability, burst war water is avoided to attack problem；Compared with single flood-diversion sluice, the automatic flood diversion of Ji Zikuidiba is washed in a pan equipped with cross flow, It can use long-range control and automatically control numerous remote gates under the conditions of flood-diversion sluice solves the problems, such as urbanization and lack administrative staff； Compared with dykes and dams are without lock floodway, concrete needs higher without the inevitable higher weir head of lock floodway if large discharge per unit Non-overflow dykes and dams, reservoir inundation is big, can not be directly to the flood diversion of beach field, and low cost of the present invention controls smaller weir using wide floodway Upper head reduces non-overflow dykes and dams height, directly can need longer overfall dam, work to the flood diversion of beach field if small discharge per unit width Journey cost is high, and the present invention is flooded small, and project cost is low；It is existing compared with existing multistage self collapsing levee dam concrete emergency spillway Concrete dividing pier form cost is high, and cost of the present invention is extremely low, and it is small routed big to wash in a pan the small water of base self collapsing levee dam floodway by multistage cross flow Water is burst greatly, and flood uncertainty problem is solved, and is realized purpose of preventing and reducing natural disasters, is solved the uncertain problem of super standard flood；With No flood diversion building compares, and geotechnological plate very floodway cost of the invention is extremely low, it allows hydraulic engineering super now to change The design theory of standard flood damaged or destroyed by flood provides technical support to establish dykes and dams super standard flood theory of preventing and reducing natural disasters.Using this hair It is bright can solve existing standard of flood it is low, without the very silt arrester of flood diversion measure, the largely River Embankment without flood-diversion sluice, canal system The problem of building, cofferdam damaged or destroyed by flood；It advantageously accounts for the problem of trans-boundary water boundary river flood diversion between country；Reduce flood-diversion sluice aging The maintenance problem of corrosion；And a kind of new way is provided for plastic garbage recycling.7. geotechnological plate very floodway of the invention: with The geosynthetics of Ye Xing very floodway compares, and increases the structure of geotechnological sole scale and shell in structure, is suitable for more Gao Shui Head higher flow rate and smaller floating material, compare, the geotechnological plate advantage that the present invention uses is can to meet an urgent need now to build, and is encountered on material War can take over civilian industry plate for use and replace geotechnological plate；Structure is simply easy to implement；Trapezoidal and closing threading is suitable for sandy land Base, the fish scale shape overlap joint of geotechnological sole squama shape mask plays drainage pressure-reducing dispersing water flow shearing force, prevents in uplift pressure, part It throws under the effect of damaged flowing pressure geotechnological sole squama shape

Unrestrained water dykes and dams burst be broken to because coupling destroy dynamical evolution, be the extremely complex presentation abbreviation that bursts in self collapsing levee dam Extremely simple mechanism draws to establish complete cross flow confluence and rushes self collapsing levee dam structure and provide fundamental basis, fills up self collapsing levee dam and set Theoretical blank is counted, is typical case with unrestrained water Clay Microstructure, when cross flow dykes and dams open the beginning with smaller depth of water spreading cross flow, dykes and dams top Road surface and downstream slope have certain impact resilience, do not break through bad, and cross flow dykes and dams downstream slope flow-shape is open channel uniform flow, When the cross flow dykes and dams top depth of water increases, open channel uniform flow erosion damage takes place in cross flow dykes and dams downstream slope, is unrestrained water dykes and dams at this time Downstream sandy soil slope headcut scour destroys initial phase, to be multistage from bursting differential design and cross flow confluence draws and rushes the design of self collapsing levee dam and mention For theoretical basis, corresponding weir headwater depth is that critical dykes and dams foot headcut scour destroys weir headwater depth H_d, mentioned for differential Quantitative design For theoretical basis；If erosion damage, dam base dam slope steepening occurs in dam base, dam slope steepening is passed to top step by step It leads, forms open channel nonuniform flow precipitation fluidised form level erosion damage step by step, constitute the fast unrestrained water dykes and dams of undermining and trace to the source level Erosion damage feature, dykes and dams are higher, and headcut scour is faster, after the unrestrained water dam base gradient is greater than sandy soil angle of repose, sand earth embankment Dam body generates the straight line landslide that inclination angle is sandy soil internal friction angle and destroys, and dykes and dams slope surface is transferred, turned in dykes and dams slope surface At folding occur Embankment Slope down stream erosion damage, the higher down stream of dykes and dams wash away hole it is bigger, incision speed is faster, cause it is subsequent directly Line landslide is faster, and quick incision is continued in bottom, and Embankment Slope down stream headcut scour is faster；When unrestrained water dykes and dams downstream slope straight line comes down It extends under the road surface of dykes and dams top, hard surface forms cantilever down stream, and road surface down stream erosion damage, scour hardening are formed at dam abutment Road bed, the cantilever road surface in Clay Microstructure downstream occur moment of flexure stress rupture in the case where self weight, water recast are used and local shedding, lead It causes Clay Microstructure to form cantilever down stream, the support of sandy soil dyke (dam) is lost after dykes and dams Clay Microstructure, in osmotic pressure, Gravitative Loads Lower generation Circular Slip destroys, and shows that dykes and dams Clay Microstructure downstream is peeled off layer by layer, is unrestrained water dykes and dams crevasse starting rank at this time Section is provided fundamental basis to determine that cross flow confluence draws to rush the design of self collapsing levee dam structure and draw the design of punching pin embankment structure；When unrestrained water dike When Ba Niantuxieqiangding loses hard surface scour protection, overflows water dykes and dams Clay Microstructure and incision erosion damage occurs, top is non-full Slow with consolidated clay incision, it is fast that bottom seepage flow is saturated consolidated clay incision, while unrestrained water dykes and dams Clay Microstructure cantilever increases, clay Sloping core overflows water dykes and dams Clay Microstructure cantilever under self weight, water pressure, soil pressure effect and stress rupture occurs and is broken, or occurs Overturning, unsaturation consolidated clay stress rupture in top is slow, and seepage flow saturation consolidated clay stress rupture in bottom is fast, the crevasse depth of water Increase, the quick incision erosion damage of crevasse Clay Microstructure, just forms unrestrained water dykes and dams and burst the stage, and then solve the reason of Clay Consolidation Topic is argued, under the conditions of critical dykes and dams foot headcut scour destroys weir headwater depth, is broken by unrestrained water dykes and dams downstream sandy soil slope headcut scour It is badly a slow process to unrestrained water dykes and dams crevasse initial phase evolution, the lower unrestrained water dykes and dams the slower, lower unrestrained water dykes and dams Evolving to unrestrained water dykes and dams stage of bursting by unrestrained water dykes and dams crevasse initial phase is also slow process；When dykes and dams weir, headwater depth quickly reaches To critical dykes and dams top incision erosion damage weir headwater depth H_u, when the critical flow flow velocity of dykes and dams weir crest is greater than road surface initial velocity, dike Dam crest downstream road surface is destroyed first, then on prolong erosion damage, unrestrained water dykes and dams Clay Microstructure loses scour protection, dykes and dams weir The critical flow flow velocity on top is greater than dykes and dams clay cut-off wall initial velocity, and incision erosion damage occurs for dykes and dams Clay Microstructure top layer, directly It connects and quickly forms unrestrained water dykes and dams crevasse initial phase, while downstream slope occurs headcut scour and destroys, and is just quickly evolved to Man Shuidi Dam breaking stage, the evolution of bursting of the unrestrained more high unrestrained water dykes and dams of water dykes and dams are faster；When dykes and dams weir, headwater depth reaches critical not erosion damage Weir headwater depth H_n, upstream water level landing downstream water depth increases after bursting due to unrestrained water dykes and dams, and dykes and dams crevasse flow velocity reduces, and works as crevasse The flow velocity of critical flow is lower than Clay Microstructure non-scouring velocity, and dykes and dams crevasse incision is slow, forms the unrestrained water dykes and dams crevasse stabilization sub stage, can To determine the residual and flood diversion ability on self collapsing levee dam.The relatively narrow jet-bedding formula self collapsing levee dam that draws is the affixed statically indeterminate structure in three faces, top Cohesiveness, the internal friction angle of portion's unsaturation consolidated clay are larger, fracture, the stress rupture that topples it is slow, bottom saturation consolidation Cohesiveness, the internal friction angle of clay are smaller, fracture, the stress rupture that topples it is fast.

The unrestrained water dykes and dams burst be broken to because coupling destroy dynamical evolution, be typical case, cross flow dykes and dams with unrestrained water Clay Microstructure It is open channel uniform flow erosion damage that erosion damage, which takes place, in downstream slope, is that unrestrained water dykes and dams downstream sandy soil slope headcut scour is broken at this time Bad initial phase, corresponding weir headwater depth are that critical dykes and dams headcut scour destroys weir headwater depth H_d；Washing away makes dam base dam slope Steepening, forming open channel nonuniform flow, precipitation fluidised form level erosion damage, the higher level of tracing to the source of dykes and dams wash away faster, Man Shuidi step by step After dam bottom slope is greater than sandy soil internal friction angle, sand earth embankment dam body generates the straight line that inclination angle is sandy soil internal friction angle and comes down It destroys, dykes and dams slope surface transfers, turning point occurs in dykes and dams slope surface and develop into down stream erosion damage, the higher down stream of dykes and dams is traced to the source It washes away faster；When slope straight line landslide in unrestrained water dykes and dams downstream extends under the road surface of dykes and dams top, parting hard surface forms cantilever down stream, Down stream erosion damage in road surface is formed at dam abutment, scour hard surface basis, the cantilever road surface in Clay Microstructure downstream is in self weight, water Recast local shedding with lower generation moment of flexure stress rupture develops as Clay Microstructure cantilever down stream, loses after dykes and dams Clay Microstructure It goes sandy soil dyke (dam) to support, the Circular Slip peeled off layer by layer is generated under osmotic pressure, Gravitative Loads and is destroyed, landslide is being washed away Under coupling destroys, cross flow dykes and dams Clay Microstructure is thinning and seepage erosion occurs, and empties roadbed, and hard surface is heavy, dynamic in self weight, water Fall damage occurs under water souring, is unrestrained water dykes and dams crevasse initial phase at this time；When unrestrained water dykes and dams Clay Microstructure top loses When hard surface scour protection, overflows water dykes and dams Clay Microstructure and incision erosion damage, top unsaturation consolidated clay anti-impact stream occurs Fast big incision is slow, and seepage flow saturation consolidated clay anti-impact flow velocity in bottom is small and the big incision of flow velocity is fast, and Clay Microstructure is in self weight, hydraulic pressure The stress rupture that unrestrained water dykes and dams Clay Microstructure cantilever occurs fracture or topples under power, soil pressure effect, top unsaturation consolidation are viscous Native cohesiveness, internal friction angle are big, and tension stress is big, and generation stress rupture is slow, bottom unsaturation consolidated clay cohesiveness, interior friction Angle is small, and tension stress is small, and generation stress rupture is fast, and the crevasse depth of water increases, the quick incision erosion damage of crevasse Clay Microstructure, with regard to shape Cheng Manshui dykes and dams burst the stage, under the conditions of critical dykes and dams headcut scour destroys weir headwater depth, overflow water dykes and dams crevasse initial phase Evolution is a slow process, and it is more lower slower to overflow water dykes and dams；In dykes and dams weir headwater depth in critical dykes and dams top incision erosion damage Weir headwater depth H_uUnder the conditions of, dykes and dams top downstream road surface occur to destroy first and on prolong, unrestrained water dykes and dams Clay Microstructure loses erosion control guarantor Hair care, which is given birth to, cuts erosion damage, forms unrestrained water dykes and dams crevasse initial phase, while downstream slope occurs headcut scour and destroys, just quickly Unrestrained water dykes and dams are evolved to burst the stage；When dykes and dams weir, headwater depth reaches critical not erosion damage weir headwater depth H_n, dykes and dams crevasse side It cuts slowly, forms the unrestrained water dykes and dams crevasse stabilization sub stage；The relatively narrow jet-bedding formula self collapsing levee dam that draws is the affixed statically indeterminate structure in three faces, top Cohesiveness, the internal friction angle of portion's unsaturation consolidated clay are larger, fracture, the stress rupture that topples it is slow, bottom saturation consolidation Cohesiveness, the internal friction angle of clay are smaller, fracture, the stress rupture that topples it is fast；The cross flow confluence of cantilever design draws punching certainly Dam inrush using top local section model test acquisition A_i、A_z。
