Description

Forbidden lamella geomembrane cloth antiseepage curtain self collapsing levee dam 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 forbidden lamella geomembrane cloth self collapsing levee dam, floodway.
Background technique
Highest dam Austria of U.S. rhovyl dam and reservoir spillway occurs 91.4 m wide, 152.4 m in flood discharge within 2017 Long, 13.7 m depth big hole starts simple secondary spillway and dangerous situation also occurs, leads to 18.8 ten thousand people's emergency escapes, " beauty such as Zhang Xiuli National Olympic's Lovell, Bernard reservoir spillway lets out slot destructive insident brief introduction and preliminary analysis " the reason of analyzing the accident, quotation " is not organized It is ready to undertake up to million dollars of expense and is only the true cause that improvement project lies on the table ", this exposure reservoir maintenance face Spillway erosion damage occurred for the problem of facing, Chinese Banqiao reservoir, Liujiaxia Reservoir, Anhui Province village storehouse reservoir, this gives Our enlightenment is: reservoir spillway has secondary overflow because of erosion damage when the reason of design, construction, management may cause flood discharge Big vast road or emergency spillway, reservoir dam and main spillway are with regard to more a safety guarantee.Warning 1: dilute part when anything crops up overflows very much The inspection that the design theory in big vast road lacks practice is also easy to be ignored, it also jeopardizes dam safety, warning 2: the single soil of high water head The weak base spillway of masonry dam dam abutment, once damaged or destroyed by flood, it directly threatens dam safety；Once China enters aging and economical into low Rise period, a large amount of reservoir spillway maintenance will also face problem, and the reservoir of especially privatization is met bankroll problem and is more difficult to Processing；Single spillway is high there is also cost and enables the extremely low problem of probability at full capacity, there is also a large amount of outdoor concrete by Aging, freeze thawing, frost heave, sedimentation, seepage erosion problem exist and enable the low steel construction corrosion problem of probability and need to furnish a huge amount of money for support Shield maintenance problem.However, we increase single Flood Design Discharge for Spillway ability now to reduce the risk of inundating the dam by flood, avoid overflowing very much The Design of Reservoirs theory in big vast road, facing single weak base spillway instead and accident occur may cause the problem of dam break, burst both at home and abroad The case on dam shows that dam break is catastrophic consequence.Japan crosses 10 years one chance floods on September 11 days 10,2015 after eagre High 20 centimetres of dyke of 4 meters of water quality standard inrush, cause the more people of 7 personnel deaths missing with it is injured, cause fortune to damage It loses；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；Day This 75 western Japan heavy rain 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 one third house, force Thousands of people climb onto the roof emergency, only very for raised path between farm fields, are resulting at least 28 people wrecked, Japanese authorities when force of rain most serious, Went out evacuation command to 5,000,000 human hairs, but these order many common people not take seriously, due to the uncertainty of flood, inrush Uncertainty, economically developed Japan inrushes year after year, and in the case where existing flood control is theoretical and technical conditions, " wolf is coming " is worldwide Social concern.How to cope with war water and attack dam break and surge and destroys lower reservoir and destroying downstream dyke causes river diversion to be empty White point.In addition, Rapid-Urbanization, remote water project management shortage of staff is problem, and national boundary river trans-boundary water flood diversion does not have Build detention basin medium or smallsized river how flood diversion, divide the maintenance of sluice management and maintenance to be problem, the silt a large amount of, standard of flood is low Ground dam, dyke, canal system slope water crossing, channel flood diversion building, a large amount of damaged or destroyed by floods in cofferdam are problems.
The reservoir for solving low water head using the method for the emerging self collapsing levee dam geosynthetics very floodway of leaf is single to overflow The problem in big vast road and numerous dykes and dams burst problem, but it is confined to low water head self collapsing levee dam, further, since not having self collapsing levee dam Design theory, it becomes the obstacle promoted and applied.Self collapsing levee dam is ancient in China and has it, and ancient times Dujiang weir just uses blown sand weir, It can be found everywhere as Japanese dyke overflows 20 centimetres of cases just burst of water, this illustrates that self collapsing levee dam has feasibility, but also has certainly Inrush dam do not burst in time cause key dam overflow dam case, furnishing a huge amount of money for both at home and abroad from the fifties, it is not tangible to carry out experimental study At the self collapsing levee dam design theory of common recognition, it becomes 60 years pendent worldwide theoretical puzzles.In modern American people's handle Self bursting dam is introduced into Design of Reservoirs, and nineteen fifty-nine E.RoyTinney introduces prototype and model in " performance of flushing from weir of bursting " text Self bursting dam systematic Study is opened in experimental study because self bursting dam super standard flood enables, probability is small, low cost, automatic opening, Advantage convenient for management causes countries in the world to furnish a huge amount of money for carry out follow-up research immediately.The F Sai Tuerke of Turkey in 1978 exists " hard surface anti-impact makes self bursting dam be difficult to the problem of bursting, and solves using jet-bedding is drawn " is pointed out in " a kind of novel spillway ". Zhang Kejian pointed out in " Zhejiang reservoir spillway building overview and related knowledge question of water conservancy " " after 75.8 flood of Henan China, The test that planning and design institute of Ministry of Water Resources and Power Industry organizes the province such as Henan, Liaoning, Zhejiang, Anhui to carry out self bursting dam in relation to design R&D institution is ground Study carefully, not only live prototype or large scale model test cost are very big, and testing data also can only explain in this kind of dam type and be somebody's turn to do Dam body under kind of experimental condition washes away situation, the analysis calculation method that can generally provide application can not be provided for self bursting dam design and Just once occurred to 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 in small-sized hilly pond reservoir ", China's research Emphasis be also draw jet-bedding and draw washing pipe, the disadvantage is that testing expenses it is high and draw jet-bedding scale, the design of spacing is needed to test and be determined, It not can guarantee in face of uncertain flood and draw in time routed, drawing jet-bedding maintenance management is also problem.Guo Jun is Swedish specially in recommendation " the long-term consolidation of self bursting dam is allowed to reference inventor in benefit " the certainly routed weir of the novel flood control water blocking formula of Hydroplus-one kind " Flood period is difficult to 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 be accurate Quantify condition of bursting, more than ten of country's use, but its dissipation and scouring requires height, cost high and topple to burst certainly to will cause very greatly It surges disaster.Pang Min points out " geomembrane self collapsing levee dam breaking is fast " " formula emergency spillway is designed from bursting ", without reference to geotechnique Can film, which protect to stay, swims the problem of dam body retardance is washed away." Chinese rivers flood control book series-Haihe River volume " Haihe River uses self collapsing levee dam, because Self collapsing levee is anti-to have the shortcomings that being unable to control, using human-generated explosives as alternative.There is presently no self collapsing levee prevent design theory, Generally general is human-generated explosives flood diversion method, and advantage can overcome consolidated clay, hard surface uncertain, disadvantage flood season pipe Once reason and explosive management require, high, explosion flood diversion is out of control.Dykes and dams burst very generally, set without the feasible self collapsing levee dam with common recognition Meter is theoretical, does not just have a complete set technology, the reason of be that present self bursting dam design theory is to quantify to reach flood as defined in specification Standard, i.e. self bursting dam start to start to that reservoir level rises to the time of normal water level and self bursting dam time of bursting coincide, and each From bursting, phenomenon mechanism is all very complicated can be solved without mathematical model at present on kind dam；At present by research technique, only draw jet-bedding self bursting dam There is similitude than ruler bulk testing greatly, the statically indeterminate structure for drawing three face consolidated clays of jet-bedding complicates the issue, and tests simultaneously The uncertainty, unlimitedness and consolidated clay and hard surface that can't resolve flood cause from the uncertain problem burst, mesh Preceding all self bursting dams by experimental design must be rare singularity lanthanon, be hardly obtained the verifying of practice；By economic technology A large amount of middle-size and small-size dams, the head-work, dyke, canal structure, cofferdam of condition limitation, specification allow super standard flood damaged or destroyed by flood, Although the damaged or destroyed by flood of magnanimity, specification allows people 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 flood-diversion sluice and dyke flood-diversion sluice, dykes and dams of the invention include reservoir dam and River and lake dyke, geosynthetics of the invention include geotechnological plate, composite geo-membrane, waterproof geotechnological woven fabric, colour bar cloth, nothing Woven fabric adds colour bar cloth, and geomembrane cloth includes dividing geomembrane, plastic film, the waterproof woven fabric of geotechnological software.
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；Hydraulic Engineering Design, management theory and technology in the urgent need to address under the conditions of being urbanization, being aging 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 Zhejiang province water conservancy in 1978 of the emerging rock-fill dams damaged or destroyed by flood mathematical model of leaf and the evolution of origin cause of formation Dynamic Coupling Water power Science Institute etc. " report of South Mountain reservoir self bursting dam experimental stage " data establishes dykes and dams and bursts mechanism, recycles leaf emerging Dykes and dams prevent and reduce natural disasters the method for design theory, establish self collapsing levee dam and prevent and reduce natural disasters design theory and complete set technology, it is outstanding to solve And pending global problem provides a kind of method.

Tunneling boring forbidden lamella geomembrane cloth antiseepage curtain self collapsing levee dam of the invention: with existing individual experimental design self collapsing levee dam knot The essence difference of structure is: designing basic difference with current self collapsing levee dam, (1) changes according to self collapsing levee dam breaking mechanism The structure on existing clay core body self collapsing levee dam, constructs that set of cheap, structure is simple, super let out super routed subtracts the forbidden lamella surged Geomembrane cloth antiseepage curtain self collapsing levee dam, according to self collapsing levee dam breaking mechanism, super to let out super the routed forbidden lamella surged of subtracting geotechnological to set of Film cloth antiseepage curtain self collapsing levee dam carries out subregion and Quantitative design, solve existing self collapsing levee dam can not solve it is probabilistic, unlimited Super standard flood problem and uncontrollable disaster of surging problem, solve the insurmountable consolidated clay in existing self collapsing levee dam, Hard surface, coarse grain diameter sandstone dam body are solved existing self bursting dam design and are tested and nothing using individual from probabilistic problem of bursting The general problem of method;(2) forbidden lamella geomembrane cloth antiseepage curtain self collapsing levee dam subregion effect is female easy sand surfing stone earth embankment dam of non-sticky Prolong on body area headcut scour destroys and straight line comes down, causes parting hard surface quickly to collapse, impervious body loses dyke (dam) support And overturning, and then cause the easy sand surfing stone earth embankment dam seepage erosion of sub- non-sticky；The sub- easy sand surfing stone earth embankment dam of non-sticky, seepage flow Destruction further cause hard surface collapsing, under the conditions of low water head, low flow velocity seepage flow with wash away coupling under quickly burst, Self collapsing levee dam obtains enough flow velocity realizations and draws punching；Coarse grain diameter or dyke (dam) containing cohesive soil utilize natural material to reduce cost While also slow down dam break using slow burst and surge disaster；Consolidated clay impervious body guarantees safety from routed condition in incision flow velocity Under, it is burst slowly using consolidated clay and slows down dam break and surge；(3) forbidden lamella geomembrane cloth replaces clay cut-off wall to avoid consolidated clay anti- The problem of seeping wall topples in headcut scour destruction and falls off, and then cause small dike dam seepage erosion, broken in headcut scour and seepage flow Under bad coupling, so that hard surface collapsing is burst and draw punching, it is to solve have the low cross flow head of hard surface, short self collapsing levee dam The key for slow problem of bursting；Using drawing the easy sand surfing stone earth embankment dam body area internal friction angle of high, the female non-sticky of punching pin dykes and dams, female sandstone Dyke (dam) punching hole is deep to divide self collapsing levee dam subregion, realizes that criterion and quantity designs self collapsing levee dam subregion；The self collapsing levee dam of cross flow subregion Surpass the ability of letting out with weir flow and slow down the water level rate of climb, depth of water spreading is bigger from faster super routed ability of bursting, self collapsing levee dam subregion Clay cut-off wall, coarse grain diameter sandstone dam body subtract and surge from bursting slowly, they slow down disaster of surging.According to self collapsing levee dam task, again The property wanted, local material have various self collapsing levee dams for choosing, and various types has the beneficial effect that: the forbidden lamella geomembrane cloth antiseepage heart Curtain self collapsing levee dam, advantage is that forbidden lamella geomembrane cloth project amount is low, the disadvantage is that maintenance is difficult, hard surface slows down from speed of bursting；Forbidden lamella Geomembrane cloth antiseepage oblique curtain self collapsing levee dam, advantage is that maintenance is held preferably, the disadvantage is that forbidden lamella geomembrane cloth project amount is big, hard surface subtracts Slow speed of bursting certainly；Forbidden lamella geomembrane cloth antiseepage curtain primary and secondary self collapsing levee dam, in the easy sand surfing stone earth embankment dam area headcut scour of female non-sticky So that the oblique curtain in sub- forbidden lamella geomembrane cloth antiseepage downstream is lost support overturning with straight line landslide, and then causes sub easily sand surfing stone Dyke (dam) seepage erosion, hard surface collapse, and small dike's dam breaking draws punching, and advantage is forbidden lamella geomembrane cloth antiseepage heart curtain project amount It is small, burst it is fast, the disadvantage is that maintenance is difficult, suitable for the self collapsing levee dam for having the requirement of hard surface quickly to burst；Forbidden lamella geomembrane Cloth antiseepage curtain self collapsing levee dam geosynthetics very floodway, high weir geosynthetics very floodway plays flood diversion Water level effect, reduces flood diversion disaster, can be used for solving short clay core body self collapsing levee dam towards the controllably automatic flood diversion of beach field From probabilistic problem of bursting.

extremely simple Mechanism is provided fundamental basis to establish complete forbidden lamella geomembrane cloth antiseepage curtain self collapsing levee dam structure, fills up self collapsing levee dam design reason The blank of opinion is typical case with unrestrained water Clay Microstructure, and it is that open channel uniform flow washes away that erosion damage, which takes place, in cross flow dykes and dams downstream slope It destroys, is that unrestrained water dykes and dams downstream sandy soil slope headcut scour destroys initial phase at this time, to be multistage from differential design and the forbidden lamella soil of bursting The design of work film cloth antiseepage curtain self collapsing levee dam is provided fundamental basis, and corresponding weir headwater depth is that critical dykes and dams headcut scour destroys on weir Depth of water Hd, provide fundamental basis for differential Quantitative design；Washing away makes dam base dam slope steepening, forms open channel nonuniform flow step by step Precipitation fluidised form level erosion damage, the higher level of tracing to the source of dykes and dams are washed away faster, and the unrestrained water dam base gradient, which is greater than in sandy soil, rubs After wiping angle, 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, There is turning point and develops into down stream erosion damage in dykes and dams slope surface, and dykes and dams are higher, and down stream headcut scour is faster；When unrestrained water dykes and dams downstream Straight line landslide in slope extends under the road surface of dykes and

designs and draws the design of punching pin embankment structure and provides fundamental basis；When unrestrained water dykes and dams are viscous When Tu Xieqiangding loses hard surface scour protection, overflows water dykes and dams Clay Microstructure and incision erosion damage occurs, top unsaturation is solid It is slow to tie the big incision of clay anti-impact flow velocity, seepage flow saturation consolidated clay anti-impact flow velocity in bottom is small and the big incision of flow velocity is fast, Clay Microstructure The stress rupture that water dykes and dams Clay Microstructure cantilever occurs fracture or topples is overflow under self weight, water pressure, soil pressure effect, top is non- Saturation consolidated clay cohesiveness, internal friction angle are big, and tension stress is big, and generation stress rupture is slow, and unsaturation consolidated clay in bottom is solidifying Poly- power, internal friction angle are small, and tension stress is small, and generation stress rupture is fast, and the crevasse depth of water increases, the quick incision punching of crevasse Clay Microstructure Brush destroys, and just forms unrestrained water dykes and dams and bursts the stage, and then solves the theoretical puzzle of consolidated clay, broken in critical dykes and dams headcut scour Under the conditions of bad weir headwater depth, overflowing water dykes and dams crevasse initial phase evolution is a slow process, and it is more lower slower to overflow water dykes and dams；?
