摘　　要：三家村堆积体位于金沙江金安桥水电站库区左岸岸坡,该堆积体主要由崩塌堆积物及坡积物形成,水库蓄水后,堆积体前缘部分被淹没,整体稳定性受到影响,可能会影响其上居民的生命及财产安全。在现场地质调查,勘探及试验成果的基础上,对该堆积体在水库蓄水后,不同的工况下的稳定性进行了分析研究,为下一步的工作提供建议。The Sanjiacun talus lies on the left slope of the reservoir area of the Jin＇anqiao hydropower project,which is mainly composed of debris and slope wash,and its leading edge is partially inundated after impounding.As a result the whole stability of the talus is affected and thus the life and property of the inhabitants living on it would probably be affected.This paper makes an analysis and study of its stability under different operating conditions of the reservoir after impounding based on the field geological investigation,exploration and test results and then puts forward the proposals for further work.
