Description
Technical field
The present invention relates to osmotic pressure load test equipment technical field, more particularly to one kind stably apply with Crack Extension
The experimental rig of osmotic pressure.
Background technology
Underground rock engineering is often under complicated geological environment, and many engineering project disasters related to underground water are (as mine
Karst declogging, Tunnel Gushing etc.) it is all because the change that seepage field external environment condition is lured in behavior into is opened up in underground, promote rock mass implosion
Gap splitting extends, is mutually communicated, and then causes geological disaster.In mechanics category, excavation behavior is defined as a kind of engineering and unloads
Lotus process, the joint fissure in rock mass by carrying out and mutual sliding, extension and interaction occur with unloading process, and to rock
The mechanical characteristic of body produces significant impact, leads to rock mass to gradually degrade and until last surrender.With resource exploitation, water power work
The continuous increase of the underground engineering depths of excavation such as journey diversion tunnel, nuke rubbish underground disposal, national defence, is related in deep rock mass engineering project
The high water pressures arriving get more and more, and the rock mass mechanics problem that high water head pressure brings has become as urgently to be resolved hurrily in Geotechnical Engineering
Frontier nature problem, and attracted large quantities of outstanding researcher to be engaged in the research work in this field.
The comprehensive achievement in research about infiltration hydraulic pressure effect at present, theory analysis and numerical simulation are two kinds of main researchs
Methods and techniques means.During theory analysis, mainly take into account the mechanical function of infiltration hydraulic pressure, and ignore seepage field pair
The bating effect of joint plane；Numerical approach methods, then be to be realized based on ripe business software platform, and the opening of business software
Send out and be also built upon on mechanical foundation, substantially as broad as long with theoretical research, theoretical research is simply realized visualization by it
?.
And it is directed to Test And Research Work few, Zhou Zhihua (uniaxial cycling load and the infiltration that infiltration hydraulic pressure effect is carried out
Hydraulic pressure lower prestress fissure rock failure test research, 2014), Chen Hongjiang (manage by crack rock coupling of stress- damage-flow
By, test and engineering Application Research, 2010), (test specimen containing three-dimensional fracture acts on fracturing in biaxial pressure and hydraulic pressure to Fu Jinwei
Test and numerical simulation study, 2015) achievement in research more representative, and the question essence closer to research object：
Zhou Zhihua devises a kind of infiltration Water hydraulic static pressure loading device (CN201120502167.X；CN201120519929.7), by oil pump
Apply a certain size oil pressure in the prefabricated built-in closure crack of model test piece, then keep oil pressure stable, to crannied body mould
Type carries out series of uniaxial compression test；Chen Hongjiang in normal triaxial chamber, by water pump to the cylinder containing insertion crack
Model applies a certain size hydraulic pressure, and keeps confined pressure steady, implements a series of infiltration hydraulic pressure examination under three axle loading environments
Test test job；Fu Jinwei devises a set of hydrofracturing priming apparatus (CN201410034987.9), and containing prefabricated built-in
Series of uniaxial and Biaxial stress test have been carried out in the rocks resin mould test specimen in crack.
In sum, existing apply the experimental rig of osmotic pressure and method, have the shortcomings that one common：It is applied
Osmotic pressure, can not keep stable with Crack Extension.Although prior art can (prefabricated crack be most advanced and sophisticated no at the initial stage of loading
Micro-crack is developed, is extended) keep permeating stablizing of hydraulic pressure on crack surface, but it is as the appearance of Crack Extension phenomenon, inside is split
Gap will occur dilatancy, such as to keep infiltration water pressure invariableness, need to supply equal-volume highly pressurised liquid to the inside of model test piece, by
In crannied body destructive process extremely unstable, slow or anxious, above-mentioned experimental rig is difficult to realize the synchronization input of equal-volume liquid, more
It is difficult to maintain stablizing of infiltration hydraulic pressure.But in Practical Project, during underground water extends with rock cranny and shifts,
Pressure is held essentially constant, and it is also the power resources that prominent water burst occurs.
