摘　　要：水库塌岸是水库运行中库岸稳定的主要工程地质问题。“两段法”塌岸预测是对水库设计洪水位上下不同地层岩性的岸坡稳定坡角进行统计,并根据图解预测最终塌岸宽度,结合地质调查,进一步预测塌岸面积(投影面积)和水上塌岸体积,在峡谷型水库工程实际应用中取得良好效果。在地质调查的基础上,运用“两段法”对某水源水库进行塌岸预测,结果基本可靠,可为后续采用处理措施提供理论参考。Reservoir bank collapse is the main engineering geological problem of reservoir bank stability during reservoir operation.The two-stage method for predicting bank collapse is to make statistics on the stable slope angle of bank slope with different formation lithology above and below the design flood level of the reservoir,predict the final bank collapse width according to the diagram,and further predict the bank collapse area(projection area)and the volume of bank collapse above water in combination with geological survey,which has achieved good results in the practical application of canyon type reservoir projects.On the basis of detailed geological survey,this paper uses the two-stage method to predict the bank collapse of a water source reservoir of a project,and the result is basically reliable,which can provide a theoretical basis for subsequent engineering treatment measures.
