Description
Technical field
The present invention relates to one kind can monitor many material joint seepage prevention systems, belong to seepage control technique field.
Background technology
Pressure-seepage Flow coming down, be squashed, play obvious action in the geological disaster such as mud-rock flow, process of osmosis not only corrosion
Take away the colloidal substance in ground and fine grained, caused it loose, also there is to Rock And Soil osmotic pressure and promote, float support, lubrication etc.
Counter productive.International Commission on Large Dams(International Committee on Large Dams)Once to global dike
Dam breaking disaster carries out statistical analysiss it is believed that seepage abnormality is the main inducement of dykes and dams slump.Count according to Chinese Water Conservancy portion, from
Since 1954 have record, China has occurred and that big dam breaking accident 3515 times, and its Medium & Small Earth Rock Dam is because of unrestrained top, seepage failure
Lead to dam break accounting more than 98%, the phase such as such as 2013 Xinjiang connection abundance of water storehouse, Heilungkiang spark reservoir, Shanxi Qu Ting reservoir
Continue dam break, all causes significant casualties and economic loss.
Seepage control technique both domestic and external is similar so far, main inclusion:Filling grouting or grout curtain, with concrete, glue
Soil, self-solidifying ash etc. are the various antiseepages of main body(Intercept water)Wall, high-pressure rotary-spray or pendulum sprinkling irrigation slurry, geomembrane or panel bedding, Gai Chong
Pressure is oozed etc..During antiseepage in nearly 40 years research, project team notices:Due to conventional art grinding in anti-seepage scheme
When studying carefully, comparing selection, all do not consider the mutual damage deterioration of construction material and carefully see evolving trend, lead to dykes and dams and its basis in antiseepage
After reinforcing or specific investment cost is too high or antiseepage body life time is too short, overall benefit is generally very low, spends millions of~number every time
Ten million yuan of maintenance fund, but can only make infiltration and antiskid index reach standard in several years, far from reaching the engineering economy longevity
Life(More than 50 years)Design requirement.Laterite(laterite)Or title admaic earth, it is widely present in damp and hot area of heavy rainfull, China master
To be distributed in the provinces and regions such as Yunnan-Guizhou, Guangdong and Guangxi Provinces, Hainan large area.Laterite is in faintly acid, and the support substance of its physical mechanics is mainly
SiO2、Fe2O3、Al2O3、TiO2Deng.Project team recent studies have indicated that:Cement, Calx etc. alkalescence reinforcement material can not only with red
In soil, silicon, ferrum, aluminum, titanyl compound occur mutually to damage deterioration reaction, also can destroy acidic aqueous media necessary to laterite cohesive strength,
Lead to the destructing of its granule and material discrete, this is exactly undoubtedly using traditional antiseepage skill on laterite ground and laterite class engineering
Art, the too low basic reason of its benefit.The construction of seepage control project and reinforcing not only will consider the short-term factors such as investment, effect, also
Should pay attention to the deterioration under environmental activity of interaction between material, microscopical structure develop, the change of different materials contact surface
Learn degraded physical isolation etc. long term factor, be otherwise not only difficult to effect a radical cure the foreign material interface seepage disease of generally existing, more
Be difficult to solve medium and small project in impervious body cost performance too low, maintenance invest too high, whole engineering normal cycle of operation too
The difficult problem such as short.
Research in impervious body association area is concentrated mainly on five aspects both at home and abroad.(1) the granule of laterite is developed and is joined with level
Design:Scholars or the origin cause of formation of analysis laterite, or the crumb structure of laterite is discussed and intercouples, or research filter material
Design and grading analysis method, or probe into the impact ... to compactness for the grain composition.(2) foreign material contact interface
Seepage flow with stable:Scientific and technical personnel are had to have studied the mechanical property of contact interface, have then discusses the larger material contacting surface of difference
Frictional resistance and shear property ....(3) antiseepage and reinforcing:There is scholar to be conceived to the infiltration impact to clay cohesiveness for the crack to grind
Study carefully, or the analysis water-soil mechanism of action, or seepage prevention design method is discussed, or enter for the Performance Evaluation Technique of impervious body
Row research, or the relation ... of analysis reservoir level and saturation.(4) to related technique of constructing:The scientific and technical personnel for example having grind
Study carefully technique and the method for quality control of high-pressure injection, the reinforcement process having inquired into weak soil having, have is then to simplify construction work
Skill and the material of cut-pff wall is analyzed ....(5) anti-seismic performance and index:There is scholar steady to cut-pff wall depth and antidetonation
Qualitatively relation is analyzed, and also scholar has inquired into the dynamic trait of soil and liquefaction phenomenon ... during earthquake respectively.Above-mentioned
In the research of impervious body association area, it is both for the emulation of the aspects such as performance, application, reparation that " single impervious material " carried out
With analysis of experiments conclusion, do not retrieve the research information related to many materials joint seepage prevention system.
In project of national nature science fund project(50869003、41462013、51069003), Yunnan Province's applied basic research
Plan key project (2013FA033), Yunnan Province's Natural Science Fund In The Light(1991E016Q、1995YI016、1997E047M、
2010ZC048), and Yunnan Department of Education of Shanxi Province(10968221、10978057), innovation team of Kunming University of Science and Technology
(14098193), Classic Course(10968137)Under subsidizing Deng multiple project verification, this project team thinks, using list through studying for a long period of time
The impervious body that one material is constituted all has obvious life-span defect:The dependence to easy corrosion grain composition of clay core wall, sloping core
Very big, anti-seepage effect is poor, and the felt earthquake of relatively low earthquake intensity will result in lax isolation or ruptures;Concrete, Calx, self-solidifying
The materials such as ash belong to strong alkaline substance, and not only cost and technical requirements are high for the cut-pff wall that it is constituted, and can be with acid laterite master
Body occurs chemical reaction to destroy contact interface, cause trickle piping in a large number;Geomembrane is too thin, is not only difficult to resist many decades and moves
The tear that bites of plant is it is more difficult to larger after the film of differential settlement formation of laterite after adaptation consolidation, earthquake make somebody a mere figurehead ....Cause
This, implement large area effectively intensive monitoring to carry out joint antiseepage using multiple material imperative to impervious body.This project
Group has understood fully the improper deterioration factor of laterite impervious body, known the highly basic such as cement to the erosion of laterite material it is proposed that pass
System impervious body reprocesses that the phase is too short, the root of difficult to reach projected life, and distinct more long-term material mutually damages evolution mechanism, sends out
Clear optical fiber geomembrane simultaneously obtains 3 licenses, and more research paper exists《Geotechnical Engineering journal》、《Rock mechanics with
Engineering journal》、《Journal of Building Materials》、《Hydroelectric generation journal》、《Advanced Materials Research》、
《Applied Mechanics and Materials》Etc. deliver on authoritative journal both at home and abroad, and write by SCI, EI etc. are international
Name searching mechanism is included.Achievement in research shows:Laterite ground and dykes and dams adopt so far antiseepage antiskid technology and reinforcement material are all
There is obvious shortcoming, erosion combined for a long time due to factors such as chemical reaction, mechanics effect, soil-water interaction, these defects are only
Only rely on material screening, the traditional measures such as structure rolls, anti-filter draining, reinforcement filling obviously all cannot be effected a radical cure.In fact, short week
Repeatedly Reinforcement is carried out to impervious body in phase, in many laterite engineerings, cause huge waste, and define
Restrict the bottleneck that development is continued in this field.Therefore, research not only has respective strengths but also can resist environmental attack, be easy to
Many material joint seepage prevention systems of the intensive monitoring of large area, have become as very urgent task.For this this project team 2014
Specially apply for and be approved project of national nature science fund project:The antiseepage new model that seepage flow induces laterite landslide is explored, and project is criticized

The operation principle of the present invention:
The Major Diseases of traditional impervious body include:Material corrosion, internal built on stilts, fracture, granule leaches, impervious effect is poor,
Bursting stress is concentrated, is lacked effectively monitoring etc., refers to the elaboration in " background technology ".
(1)The present invention adopts " integument " of high intensity and flexibility, makes somebody a mere figurehead, ruptures in order to solve above-mentioned inside, granule is filtered
Go out, the medium difficult problem of bursting stress collection.Taking the core-wall commonly using in dykes and dams as a example:Traditional core-wall is generally rolled with clay filling
Form, under the long term of Pressure-seepage Flow, soil particle corrosion leaches, built on stilts inevitable within core-wall, if not in time plus
Solid then easily developing into and collapse;In the presence of larger earthquake load, core-wall is easy to rupture, and seepage flow drastically deteriorates, if speedily carrying out rescue work not
Dam break will be led in time.In the present invention, traditional core-wall(As shown in Figure 4)It is used only as the posting in new joint seepage prevention system
Body, and it is no longer antiseepage main body, therefore it ruptures, collapsing all to cause seepage flow to deteriorate;The integument of high intensity constrains the heart
The deformation of wall is so as to leach in granule, the change of shape after internal built on stilts, fracture is substantially reduced, the bag in body series in addition
Covering layer and impervious monitor layer are all flexible, can adjust automatically shape adapting to the small deformation of posting body, effectively prevent should
Power is concentrated.Therefore the anti-permeability performance of this invention is not maked somebody a mere figurehead by substantially above-mentioned inside, is ruptured, the disease such as granule leaches, stress concentration
Impact hence it is evident that extending the bulk life time of seepage control project.
(2)The present invention adopts " impervious monitor layer ", and in order to solve, above-mentioned impervious effect is poor, granule corrosion leaches, material is invaded
The difficult problems such as erosion.Achievement in research shows:The infiltration coefficient of clay core wall is generally 10-4~10-7Cm/s, and present invention employing is anti-
Oozing main body is optical fiber geomembrane, and its infiltration coefficient is only 10-11~10-12Cm/s, therefore its impervious effect is significant improve, significantly drop
Osmotic pressure after low film and seepage discharge, and then effectively reduce and pass the corrosion of carrier granular and leach.Parcel, impervious while,
The material of posting body is also kept apart by optical fiber geomembrane and carbon cloth with dam shell, basis etc. comprehensively, thus avoiding antiseepage
Body and other materials occur interracial contact to corrode hence it is evident that extending the life-span of engineering.
(3)The present invention adopts " impervious monitor layer ", in order to solve a difficult problem for above-mentioned effective monitoring.Traditional impervious body is limited to make
To overall disturbance, the quantity of sensor is tangible very little, the life-span is too short for valency and probe, the development for seepage flow and deterioration be difficult to into
The effective and long-term monitoring of row.In the present invention adopt monitoring main body be optical fiber geomembrane, using distribution type fiber-optic therein as
Intensive sensor, this novel sensor is corrosion-resistant, life-span length, can the temperature of each point, STRESS VARIATION in long term monitoring geomembrane,
And using " temperature comparisons are abnormal " and " stress contrast is abnormal " as the judgment basis of geotechnological film rupture, seepage flow deterioration.Geomembrane
Damaged part will appear from concentrative seepage, the flowing of water body lead to temperature herein, stress and breakage before with unbroken nearby
Position is all clearly distinguished from, and by the abnormal damage location that can determine that geomembrane of the contrast of time domain, face domain Monitoring Data, refers to
The optical fiber geomembrane patent of invention description of granting authorization(ZL201010109990.4;ZL201010109987.2).
The invention has the beneficial effects as follows:
(1)Solve the difficult problem that traditional impervious body drastically deteriorates in fracture, internal built on stilts rear seepage flow
Traditional impervious body easily ruptures under earthquake load;Under the long-term corrosion of Pressure-seepage Flow, cannot inside impervious body
Avoid carefully seeing built on stilts.Traditional impervious body fracture or internal built on stilts after seepage discharge substantially increase, the piping that thus causes, draw brush and
Passage makes crack drastically expand with built on stilts, leads to Rock And Soil landslide or caves in.
In seepage prevention system proposed by the present invention, traditional impervious body is only used as posting body and uses not as impervious body, because
This its fracture or built on stilts all will not change seepage discharge.Integument in the present invention and impervious monitor layer are flexible material, are passing
Carrier fracture, internal built on stilts or even after caving in, can adaptive deformation automatically, significantly reduce the outflow of granule, and can tie up
Hold the basic body of transmission load, avoid stress concentration, thus just effectively prevent the disease development of seepage flow and deteriorate.
(2)Prevent the destruction to impervious body for the animals and plants
Clay class, geomembrane quasi-tradition impervious body pierce through to the growth of plant, the tear that bites of animal all lacks defence energy
Power, this is also the major reason that traditional impervious body wrecks.Assembled scheme in the present invention adopts the carbon cloth of high intensity
Or steel wire or geotextile, as full surface integument, can effectively resist the destruction to impervious body for the various concentrated stresses.
(3)Block the mutual damage deterioration of impervious body and other materials
Concrete, volcanic ash, self-solidifying ash class impervious body all belong to basic matterial, occur for a long time with acid laterite dykes and dams major ingredient
Chemical reaction, product is solvable or be powdery, is easily taken away by Pressure-seepage Flow, thus leading to traditional impervious body to occur thin to see pipe
The disease such as gush.The present invention adopts corrosion resistant integument and impervious monitor layer, and posting body and dykes and dams major ingredient are effectively isolated and are come,
Greatly reduce the mutual erosion of material.
(4)Permanently effective monitoring can be implemented to seepage flow
In the present invention adopt impervious monitor layer be the optical fiber geomembrane having obtained 3 patents for invention, using light
Fine sensing technology and related spectral theory, all enable long-term intensive Quantitative Monitoring to seepage discharge and its mutation.Therefore, originally
Impervious body can early warning seepage flow disease, effectively take precautions against the ground landslide that abnormal seepage flow leads to or dykes and dams be squashed disaster.
(5)The position of disease can be made a definite diagnosis
After disease in traditional impervious body, ease point can only be flowed out according to the water of the water rotation of dykes and dams upstream and downstream and come substantially
Judge the position of disease.But due to the reason such as the crack of each layer of dykes and dams is corresponding, seepage flow spread in dam material, this disease positions
Error very big, often can only expend several times or even the cost of decades of times carries out universal impermeable management.The temperature at seepage abnormality position
Degree, the obvious difference all with normal portions for the stress, the impervious monitor layer adopting in the impervious system of this joint can predict each point temperature
Degree, the mutation of stress, therefore, it is possible to make a definite diagnosis the position of disease, thus save considerably to piping or native the speedily carrying out rescue work the time of stream.
(6)Save construction costs, disaster reduction and prevention
Seepage failure is the main reason that is squashed of dangerous condition and leading to of dykes and dams, China be in the world dykes and dams quantity at most,
The most country of sick dangerous section's journey, government all takes out nearly hundred billion funds every year for various dash, the reinforcement of antiseepage.Send out for this
The many materials joint seepage prevention systems of bright proposition it can be avoided that the material corrosion that generally occurs, internal built on stilts, fracture, granule leaches,
Seepage flow such as drastically spreads at the disease danger, and can quickly and accurately position the seepage abnormality position of impervious body, saves valuable when speedily carrying out rescue work
Between and reinforce expense.Its application category will obtain rapid expansion, gradually replaces high pressure jet grouting, concrete cut etc. high
Your structure, thus produce significant economic benefit under the premise that security is guaranteed.This technology is for the safety improving retaining works
Performance, the cost performance improving impervious body, obvious reinforcement expense saving dykes and dams etc. are all of great importance, and can effectively subtract
Few dykes and dams are squashed the generation of disaster.
