该文分别就降雨强度、有无植被等不同参数情况下的边坡稳定性进行了数值模拟，并讨论各种工况瞬态过程中边坡安全系数的变化情况。研究结果表明：雨量一定，历时越长，安全系数越小；吸力摩擦角大小的变化对降雨边坡稳定性呈线性关系；植被护坡对边坡稳定性的作用在中雨情况下得以最大发挥。

Based on the Geo‐studio software ,the simulation of the seepage field of pore water pressure was introduced into the limit equilibrium method of slope stability with the numerical simulation of the dif‐ferent parameters in consideration of the rainfall intensity ,with or without vegetation etc .The changes of the slope safety factor under various transient conditions were also discussed .The results showed that the longer the rain falls ,the smaller the safety factor is ;a linear relationship exists between changes of suction friction angle and slope stability in rainfalls ;the slope protecting vegetation effects maximally in moderate rains .
