| Abstract: | Ganhaizi landslide is located in Dadu River Basin,which has large scale volume.In order to study the stability of the landslide,on the basis of researching the basic characteristics,deformation and failure of the landslide,its stability and stress-strain features were then calculated and analyzed by limit equilibrium method and finite difference method,which mainly analyze landslide′s deformation features from the respect of the deep layer,shallow layer and local stability. The results of the analysis are in line with the macro-geological phenomena.Through qualitatively and quantitatively analytic judgements,it is shown that the shallow sliding body in the storm conditions will be in the state of limit equilibrium,and deep sliding body in seismic condition will still be in the basic steady state.The result obtained will provide a reliable basis for the future landslide prevention work. |
