摘　　要：利用GLE通用条分法和强度折减法,研究了滴水崖Ⅰ号滑坡天然状态和饱水状态下的稳定特性,结果表明滑坡在天然状态下是稳定的,饱水状态下会失稳。同时滑坡在地震作用下存在失稳情况,降雨条件下难以满足工程安全等级。With GLE generalized limit equilibrium method and strength reduction method, this paper studies the stability characteristics of Dishuiya Landslide No. 1 under natural state and saturated state. The result indicates that landslide is stable under natural state but unstable under saturated state. Meanwhile, landslide loses stability by any possibility under earthquake effect, so it is difficult to satisfy the safety class of the engineering under rainfall condition.

关 键 词：滑坡 降雨 地震 安全系数 稳定性
