Study On Numerical Analysis Of Rock Slope Stability

At present when our country is in the rapid growth of economic construction period,the number of various types of bridges and civil buildings is in rapid growth.There is a large number of rock slopes in the sitting and construction process of the above projects.When there are large deformation and failures,it will cause many serious consequences.It'll not only cause the project itself destroyed but also great economic losses even casualties.So the problem of slope stability is beginning to receive more attention.Rock is a mixture composed of many pores,a variety of mineral grains and cement.After millions of years of geological evolution and tectonic movement of complicated post,micro pores and cracks of rocks will contain the random distribution.On the macroscopic scale,natural rock is cut by a variety of geologic structure planes.These important features make it become a complex and special rock materials.It is not discrete medium or continuous medium but continuous and discrete coupling medium.The deformation and failure of slope is a long-term change process.The stability of slope is affected by internal and external factors and other conditions.Internal factors include:type and nature of rocks and soils of slopes,slope geological structure,the shape of the slope,etc.The external factors include:the climatic conditions,the weathering,slope vegetation,human engineering activities,etc.In certain engineering geology conditions,some factors have great influence on the stability of slope,but some smaller.It means that the contribution of the influence factors of slopes instability is different.It is of great significance to the design and prevention treatment of artificial slope to slope destabilization of disaster to find out the main influencing factors of slope instability.This paper is based on strength reduction and make application of finite element analysis software ABAQUS to calculate and analyze the main internal factors of the slope,and to explore the influence on slope stability and deformation level and sensitivity study.The research results show that:the slope safety coefficient Fsand some influence factors are of significant relationships.According to the results of the analysis of each influencing factor,it will benefit for slope reinforcement according to the main influencing factors.
