摘　　要：龙开口水电站右岸发育有规模巨大的变形体,近750万m3,其稳定性直接威胁枢纽建筑物的安全。根据边坡稳定性的分析成果,研究了锚索抗滑桩以及开挖减载2种方案。通过技术经济比较,推荐了以锚索抗滑桩为主、坡内外截排水为辅的综合治理方案。施工期监测资料表明,稳定性分析的成果及推荐的加固方案合理可靠。There is a deformed slope with a volume about 7.5 million cubic meters on the right bank of Longkaikou Hydropower Station. Its failure will threaten the safety of dam. According to the stability analysis of deformed slope, two reinforcement schemes of anchor cable slide-resistant piles and slope excavation are studied. By technical and economic comparison, it is recommended to reinforce the slope with anchor cable slide-resistant piles, and at the same time, excavating drainage holes as a supplement. The monitoring during construction period shows that the stability analysis and the reinforcement scheme is reasonable and reliable.
