Based on investigation and analysis on natural features, deformation and failure phenomena and deformation characteristics of the landslide, the mechanism of various factors （ intrinsic and extrinsic） affecting the geology are analyzed and studied ; and then the safety margin of the stability is calculated according to the rationale of two-dimensional rigid equilibrium limit and the relative sensibility analysis among these factors is carried out. Through analysis on the value distribution law of the percent effect, the various extrinsic factors are classified hierarchically by the degree of effect offering strong technical basis for landslide stability analysis, treatment design and construction.
