Chuff Shan scenic area of the mouth slope for mining completion,and to cut slope,backfill restoration of the complex type of slope,the artificial fill and natural excavation of the slope deformation and failure mechanism of the study,for the restoration of similar projects in the future has important significance. In this paper,FLAC31' finite difference method and the combination of limit balance method analysis means of painting mountain scenic spot uncompromising slope stability to study,through the establishment of non-homogeneous three-dimensional model analysis of C2,C3,C4 uncompromising slope in natural and rainfall state of displacement deformation and stress distribution,and the stress concentration area using limit balance method to calculate its stability coefficient,In the combination of the two methods more accurate to find the position of the landslide slide zone,and the landslide under different conditions of the stable state,and comprehensive finite difference method and limit balance method calculation results of Chuff Shan C2,C3,C4  mouth slope proposed targeted prevention  measures and suggestion.
