In order to analyze the influence of rainfall on the unsaturated slopes " stability , in this paper , the change of seepage field in various soil slopes under the condition of rain infiltration is studied based on the saturated - unsaturated seepage theory 为了分析在降雨入渗条件下，非饱和边坡渗流场的变化情况及其对边坡稳定性的影响，本文利用饱和-非饱和渗流理论，对在不同降雨条件下的具有不同材料特性的土质边坡的渗流场变化进行了模拟研究。
The reason for the failure of loosely residual soil slopes triggered by rainfall is that the contractive failure caused by the penetration of rainfall , giving rise to a high excess pore pressure which reduces shear strength of the soil . the soil is prone to flow slide after failure under the action of gravity due to its high moistu re content 蒋家沟地区坡残积土斜坡在暴雨条件下的破坏是由于降雨入渗导致土体发生剪缩破坏，破坏后土体的孔隙水压力升高形成超孔隙水压力、土体强度降低、破坏迅速扩展所致，因而大多数斜坡呈流滑型破坏并具有突然性破坏特点。
