| 摘 要： | 在对滑坡自然形态、变形破坏现象及滑坡变形特征的调查分析基础上，分析研究了各影响因素(包括内因和外因)对滑坡的地质作用机理，依据二维刚体极限平衡原理进行滑坡稳定性安全系数计算，开展各影响因素之间的相对敏感性分析。通过影响比例的数值分布规律分析，实现各外部影响因素影响程度等级化归类，为滑坡稳定分析、治理设计及施工提供有力的技术依据。

| Abstract: | 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. |
