摘　　要：水电站库区斜坡失稳现象发生在水位大幅抬升和下降期间,需采用多种技术手段并结合孕灾地质条件分析,判断可能存在地质灾害安全隐患的区域,并对其逐一调查,对同一隐患区域水位升降前后斜坡的稳定性对比分析,然而水电站蓄水后库区沿岸地质灾害野外调查往往造成困难。本文以白鹤滩库区(会东县段)沿线地质灾害隐患外业调查为例,对水电站库区涉水地质灾害隐患野外调查工作方法初步总结。Slope instability in hydropower reservoir areas often occurs during significant water-level fluctuations.Multiple technical approaches,combined with analysis of disaster-predisposing geological conditions,are required to identify potential hazard zones.Field investigations and comparative stability analyses before and after water-level changes are essential but challenging post-reservoir impoundment.Taking the Baihetan Reservoir(Huidong section)as an example,the field investigation methods for water-related geological hazards were preliminarily summarized.
