Description
Technical field
The invention belongs to geomechanical model test device technique field, being specifically related to a kind of geomechanical model test device for testing Rock Slope Stability.
Background technology
The mankind are being engaged in the process of producing and build, and the engineering activity such as construction of hydropower facilities, constructing road, often forms numerous rock side slopes.This kind of side slope is usually not only high but also steep, complex geologic conditions, environmental factor is severe, not only there is strong Unloading Effect, the rock side slope accident event also having the multifactor synergy such as reservoir filling, precipitation and excavation to cause, bring serious loss to people's life and property, cause construction delay thus and the indirect loss produced is inestimable especially.Therefore, the stable problem of rock side slope, concerning the safety of engineering construction and run duration and economic benefit, is studied it and is had important practical engineering value and economic worth.
Slope stability analysis is research contents important in Geological Engineering and Geotechnical Engineering always, early stage research is mainly carried out from two aspects: one is method for qualitative analysis, the method is that geologic condition residing for side slope and landslide destructive characteristics come environment that analysis of landslide occurs and mechanism, mainly pass through engineering geological investigation, the major influence factors of analyzing influence slope stability, the mechanical mechanism etc. of possible deformation failure and unstability, comprise and the genesis and evolution history of strained geologic body is analyzed, thus provide the stability that is evaluated side slope and development trend illustrates qualitatively and explains.Conventional method has natural history analytic approach, engineering analog method, graphical method etc.Two is according to the resistance to overturning of rigid Limit Equilibrium theory calculate side slope under limiting equilibrium.Limit equilibrium method be a kind of engineering uses at most, the most ripe quantitative analysis method, its advantage is when not providing malformation image under effect of stress, still can provide conclusion more accurately to the stability of structure.
After the eighties, stability of slope Journal of Sex Research enters the flourish stage, the theory of computation and computer technology fast development, and numerical simulation technology starts to be widely used in stability of slope Journal of Sex Research.Numerical simulation method is the method for a class stress ~ strain analysis, in landslide, particularly engineering slope excavation and estimation of stability, have more application.It analyzes distortion and the stable problem of given section by the stress of analysis of landslide construction inner, strain.Adopting at present more in slope analysis is the method for numerical simulation such as Finite Element and method of finite difference.
Because the scope will simulating rock mass slope is comparatively large, Tectonic Rock Mass is complicated, adds the complicacy of mechanical model, adopts said method to be difficult to the true collapse state of accurate analysis rock mass so far, and is difficult to the Back Analysis of Actual Safety Degree evaluating high slope.
For high slope stability analysi problem, people often adopt geomechanical model test method to research and analyse.Geomechanical model test is a kind of method of according to certain principle of similitude, specific engineering geological problems being carried out to reduced scale research, the fundamental purpose of test be under the effect of research various buildings outer load ultimate bearing capacity, damage-form, failure mechanism and distortion distribution character.The research contents of geomechanical model test is not limited only to a certain state under primaryload, the more important thing is research under cumulative load action until the whole change procedure destroyed, it adopts real physical entity, to meet material similar, especially under mechanical condition is similar, go the relation reflected really between tectonic structure and engineering construction, demonstrate the result that engineering construction produces rock mass impact and the impact of rock mass deformation on fabric structure more intuitively.
In Rock Slope Stability geomechanical model test, the block combination of general analog material simulates many fissuted mediums rock mass, the weak structural face of analogue enlargement stability of slope, thus the stability against sliding of research slope rock mass, the actual effect of failure mechanism and strengthening of foundation measure.
