摘　　要：考虑边坡的渗流作用力与含水率,以水位线在滑面上、下的临界平衡为基础,推导在降雨条件下边坡稳定性的极限平衡条分法计算式,结合基质吸力与渗流力的强度折减法,实现地基在降雨条件下的稳定性分析。Considering the seepage force and moisture content of the slope,based on the critical equilibrium of the water level line on the sliding surface and the bottom,the paper deduces the calculating formula of the limit equilibrium point of slope stability under rainfall conditions,based on the strength reduction method of matrix suction and seepage force,the stability analysis of foundation under rainfall condition is realized.

关 键 词：边坡失稳 强度折减 降雨入渗 抗剪强度
