摘　　要：硬梁包水电站地震地质背景复杂,闸址区50年超越概率10%,基岩水平地震动峰值加速度达260cm/s2。金蝉坡滑坡位于库区左岸,近坝约1.4km,水库蓄水后将淹没其坡脚,受库水消落及掏蚀等作用下,在水库蓄水和地震等工况下存在复活失稳可能,对大坝及其对岸移民安置点存在较大影响。本文对其稳定性进行了分析评价,并提出了工程治理措施建议。The Jinchanpo Landslide is located on the left bank of reservoir bank of the Yingliangbao Hydropower Station, about 1.4 km from the dam, which lies in seismic active region. This paper assesses stability of the Jinchanpo Landslide and makes suggestions on control measures.
