摘　　要：暴雨是影响黄土滑坡稳定性的重要因素,本文以陕西-黄土滑坡为例,利用有限差分法FLAC-3D软件对在自然和暴雨条件下黄土滑坡的变形进行数值模拟分析。根据数值模拟结果,得到滑坡体在自然状态下和暴雨状态下的变形特征和塑性分布特征,确定了滑坡体变形特征与滑坡稳定性间的联系,为黄土滑坡的稳定性评价提供必要的理论依据。The hard rain is an important factor influencing the stability of loess landslide.This paper analyzes the loess landslide deformation under natural condition and rainstorm condition with FLAC-3D by the example of a loess landslide in Shaanxi.The deformation and plastic distribution characteristics of landslide under natural and rainstorm conditions are simulated numerically.The relationship between the deformation characteristics of the landslide body and the stability of the landslide is determined.
