Analysis And Research On Slip Field Of Rock Slope Based On Geometric Shape Of Rock Mass

Landslide in the world is one of the most serious disasters,it has a huge impact on human property and life safety,almost every country has occurred large and small landslide.In China,landslides are also frequent and widely distributed,especially in some southwest regions.Due to the special influence of topography and climatic conditions,landslides in these regions are often characterized by large scale,large number,large destructive force and complex failure types.There are many factors leading to the failure of the slope,which are usually affected by the geological environment of the slope,the internal factors of the rock mass type and characteristics,as well as the engineering load such as rainfall and earthquake.The forms of slope instability are also complex and variable,which may be mainly in some forms,accompanied by other failure modes of comprehensive failure.In many types of slope,rock slope is usually composed of rock mass.Under different interference,the geometry of rock slope will change and the failure law will also change.In this paper,the stability of slope with transitional structure is studied.The SOC(self-organization activity)behavior inside the transitional rock mass structure of the rock slope under the interference of static and dynamic loads is studied by triaxial simulation test(reduced in scale of 1:10).This paper discusses the change law of the sliding surface caused by static and dynamic loads in the rock mass structure,and studies the stability of the rock slope through comparative analysis of the test results.By using c-m yield criterion theory,the slip difficulty degree under static load and after dynamic load interference was analyzed,and the slip failure probability of rock mass structure and the variation law of shear strength were studied.The conclusion of this paper is :(1)anti-slip is related to particle size,particle shape and density.(2)after being disturbed by dynamic load,there are two possibilities: one is immediate landslide disaster of the rock slope;the other is self-organization of rock particles,which tend to be compact and stable,which is mainly related to factors such as slope foot,confining pressure and loading mode.
