摘要

针对降雨入渗土坡的稳定问题，建立一个考虑水力渗透系数特征曲线、土-水特征曲线以及修正的Mohr-Coulomb破坏准则的非饱和土流固耦合有限元计算模型，进行雨水入渗下非饱和土边坡渗流场和应力场耦合的数值模拟，得到非饱和土边坡变形与应力的若干重要规律。研究成果为降雨入渗条件下非饱和土边坡的稳定分析提供了基础。

Abstract

In order to solve the problem of slope stability under rainfall infiltration

this paper presents a flow-deformation coupled finite element analysis model of unsaturated soil which considers hydraulic conductivity curve

soil-water characteristic curve

modified Mohr-Coulomb failure criterion; and the process of infiltration into an unsaturated slope under rainfall and its effect on soil slope behavior are examined using this analysis model. Some important conclusions are drawn after analyzing the stress field and deformation field of unsaturated soil slopes. This paper provides a basis for stability analysis of unsaturated soil slopes under rainfall infiltration.
