摘　　要：分析了某复杂地质条件高边坡在强震作用下可能出现的失稳模式。采用有限元软件分析该边坡开挖前后在天然状态、强地震作用和强降雨等工况下的稳定性。针对强震作用下的边坡稳定性问题提出了两种解决方案,通过比较建议采用分台阶削土放坡的加固方法。The failure mode is investigated for a high slope with complex geological conditions due to strong earth loading. Considering excavation construction, strong earthquake, raining and seepage conditions, the sta- bility analysis of the high slope case is performed by using finite element method. Two methods for high slope re- inforcement are given and discussed according to the stability problem. Then reinforced muhi-step excavation is proposed to reinforce the slope.
