摘　　要：随着我国西南地区水电建设的发展,水库蓄水后导致的坍岸现象常有发生。以在建的某水电站近坝库区右岸某松散堆积层边坡为研究对象,通过初期蓄水后出现的岸坡变形破坏迹象,以及对正常蓄水位条件下岸坡稳定性计算分析,揭示了此类边坡的坍岸机理。在此基础上,根据坍岸涌浪预测的相关经验公式,对大坝部位可能出现的涌浪高度进行了分析和评价。With the hydroelectric development in southwest China, reservoir bank failure caused by reservoir filling is becoming more and more common. Taking a loose talus slope on the fight bank near dam of the reservoir at a power plant under construction as an example, the signs of the slope deformation failure following the initial impounding and the slope stability at the normal water level are calculated and analyzed. It reveals the mechanism of bank failure of this kind. Based on the research above, the possible surge height at the dam are analyzed and evaluated according to the related emoirical formula for bank failure and surge orediction.
