Description
Technical field
The utility model is related to earth and rockfill dam safety testing field, particularly belongs to a kind of superficial soil layer Crack Detection technology, more
It is further a kind of device of resistivity method Quick Measurement of Soil stone core wall dam top layer fracture spaces feature, the utility model is mainly fitted
For the top layer crack perils detecting of the job facilities such as reservoir, pond on a hill, dyke, water channel, tailing dam, roadbed, it is equally applicable to big
Displacement follow-on test and Subsidence Land in Coal Mining Area table that the dynamic control of dam hydrofracture grouting surface crack telescopic process, slip mass are wriggled
Layer subsides the test job etc. of mechanism.
Background technology
Earth and rockfill dam is most widely used in China's dam type, the most retaining works form of quantity, especially medium and small
Very important status is occupied in the storing facilities of waters such as type reservoir, pond on a hill, is the supply and demand for ensureing the daily production of the people, life
Wave and importantly act on.However, generally earth and rockfill dam is because running the time limit, basic engineering, construction quality, construction material and daily pipe
Under the complicated factor comprehensive functions such as reason, cause either to be internally formed obvious or latent staggeredly crack on dam body surface, by it
The refinement of extension direction is divided into Craquelure, longitudinal crack and transverse crack.Dam top layer crack defect phenomenon, particularly with newly-built or
The crack disease danger problem on the core wall dam top layer after the completion of reinforcement, it destroys the globality and stability of core-wall, office significantly
Portion may cause seepage failure or overall structure security not enough, the normal operation safety of crisis dam.
The characteristics of having adaptive deformation and self heal due to earth and rockfill dam, use normal to dam structure of general crack has no
Hinder greatly, but constantly extension, insertion, the deterioration under intrinsic and external motive is acted on of some cracks, the service life of earth and rockfill dam is reduced, draw
The disease events such as the dam body for having sent out local collapses, comes down, seepage.Especially for the clay after the completion of newly-built or reinforcement
Core wall dam, if occurring crack on dam crest antiseepage top layer not only affects the overall appearance effect of dam, and with the standard of hydraulic engineering
Change management to run counter to, it is also possible to hide potentially security hidden trouble.In a word, the sky in clear and definite crack is had to for earth and rockfill dam crack
Between Distribution Characteristics and proterties, the demonstration to cause causes of cracks provides support data, so as to pointedly choose appropriate
Renovation technique and material and instruct the prophylactico-therapeutic measures of dam running to work, reach the effect for preventing trouble before it happens.
The acquisition of the spatial parameters such as earth and rockfill dam fracture width, depth, trend, routinely takes the means of excavation because destroying soil
Body original state internal structure, operating efficiency is lower, is vulnerable to the impact of natural conditions, and certainty of measurement does not reach requirement, the party
Method is alternatively；The methods such as infrared thermal imagery method, global positioning system, 3 D laser scanning, two dimension shooting are because taking
With higher and larger by external interference, though having the advantage of " visible i.e. gained ", can't see and vertically go up crack interested
, also there is actual operating force not in change, be really achieved all-round popularization and use also in terms of prediction and predictive monitoring
There is gap.In recent years, using differences such as the elasticity between medium, density, electric conductivity, dielectricities as the lossless inspection of basis of characterization
Survey technology is rapidly developed, and efficient, accurate, perspective advantage has been given play in crack of soils detection.It is with resistivity method
Example, has obvious resistivity contrasts as research object, typically by dam body surface by the use of crack body and surrounding soil
Arrangement multiple tracks electrode, explains, image is intuitive and reliable using electrical instrument gathered data and with reference to software kit, special according to its development
Point and variation characteristic, so as to judge the approximate location and width in crack.Compare previous technical method, test speed compared with
Hurry up, cost is lower.
Crack is the complexity " geologic body " with certain space form, and the space characteristics for studying crack are had to based on complete
Office's observation, but current Dynamic Non-Destruction Measurement is focusing only on and can not annotate complete splitting by obtaining the two dimensional image in crack
Seam rule, and vertical depth judgement is also mingled with human error.Additionally, Dam Crack is constantly development ground, the crack on dam body surface
Possibly progressively deteriorate what is formed by latent, potential crack, for the detection work in crack should not be limited to current one
The detection of secondary property, multiple, multi-faceted should more fully monitor, adequately find out crack in dam body Spatial Distribution Pattern (crack
Distribution, depth, aperture and ductility), while the cause and effect that fracture is produced has apparent, deep, dynamic understanding, enter
And scientifically formulate early warning and processing scheme.
