摘要
降雨是诱发滑坡发生的主要因素,分析了降雨入渗对斜坡土体的物理、力学性质产生的影响,通过对实例的数值模拟研究,揭示了边坡变形破坏受降雨影响的特征。提出在常规边坡稳定、变形破坏分析计算中应考虑降雨入渗的影响。
Rainfall is the major factor to stimulate landslide. In this paper,the influence of rainfall infiltration on slope soil mass is analyzed. The relationship between deformation and rainfall is analyzed by finite element method. It is suggested that rainfall infiltration should be considered in general analysis method for slope stability and deformation.
