摘要：

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.
