小型水库普遍存在坝基清基不彻底，其主河床段有较厚的软弱土层，该土层易造成坝坡产生深层滑动。本文根据实际工程案例，对坝体上游坡出现的滑坡加固处理方案进行分析，除采用常用的坝脚压重提高坝坡稳定性外，另沿上游坝脚纵向布置双排高喷桩，套孔相连，桩体切断坝基软弱土层，避免坝基软弱土层向库区蠕动变形，达到满足坝坡稳定设计的要求。

The clearing and stripping of dam foundation for small reservoirs is generally not complete. Due to the thick weak soil layer in main river bed, it can result in landslide. Based the actual case, the reinforcement treatment plan for the landslide of up-stream dam slope is analyzed. Except for commonly weighting in dam toe in order to improve the stability of dam slope and adopt-ing high pressure jet grouting pile in the upstream dam toe in order to cut the weak soil layer of dam foundation and avoid the creep deformation of weak soil layer in dam foundation, the stability of dam slope is satisfied.
