摘　　要：在尼尔基水利枢纽工程库区坍岸现状调查基础上,通过坍岸区土体稳定角度统计及参考经验数值,类比同流域其他工程资料,选取坍岸水下的稳定坡角和水上稳定坡角。根据坍岸剖面的地形地质资料,采用图解法预测坍岸宽度,并用卡丘金公式校核。Based on the present situation investigation of the bank ruin of reservoir area of Nierji hydro project,the paper selects the stable slope angles above and under water by the statistics of stable slope angles of soil in bank caving area, the empirical reference value and the analogy data of other project in the same river basin. Based on the topographic and geological data of the bank ruin profile, the graphic method is used to forecast the width of the bank ruin, the result is verified by using the Kachugin formula.
