摘要： 以某水库大坝西侧山体滑坡为研究对象，采用FLAC3D数值模拟软件分析了滑坡治理前后天然和暴雨工况下的滑坡稳定性。稳定性分析结果表明，治理前在天然工况下，最大位移约4.71 cm，坡体基本稳定，但在暴雨工况下，坡体滑动剧烈，最大位移达到4.01 m，坡体处于不稳定状态；治理加固后天然工况下最大位移减小到2.08 cm，暴雨工况下坡体最大位移减小到10.42 cm，均明显减小；抗滑桩治理滑坡效果较为理想，达到预期治理效果。

Abstract: Taking the mountain landslide on the west side of a reservoir dam as the research object, the authors use FLAC3D numerical simulation software to analyze the stability of landslide under natural and heavy rain conditions before and after landslide treatment. The results show that the maximum displacement before treatment is about 4.71 cm under natural conditions and the slope body is basically stable. However, under the condition of heavy rain, the slope is severely slipped, the maximum displacement reaches 4.01 m, and the slope is in an unstable state. After treatment and reinforcement, the maximum displacement of the slope decreases to 2.08 cm under natural conditions, and 10.42 cm under heavy rain conditions. Anti-slide piles are ideal for controlling landslides and achieving the desired treatment effect.
