摘　　要：水库塌岸是影响水库工程成败的重大地质灾害问题。众多学者提出了许多塌岸预测理论及方法。通过权衡各种方法的利弊，采用极限平衡搜索预测法、FLAC3D数值模拟预测法、卡丘金法3种方法对大华桥水电站水库拉古和大华滑坡体进行塌岸预测，研究表明：极限平衡搜索预测法、FLAC3D数值模拟预测法这两种方法的预测结果较为接近和合理，为水库库岸的防护设计提供充分的依据。The reservoir collapse is a significant geological disaster which affects the reservoir project＇s success. Many scholars proposed various predicting theories and methods. The advantages of different methods considered, three methods are applied in this article to analyze the possibility of reservoir collapse in Lagu and Dahua landside mass of Dahuaqiao hydropower station reservoir, i.e. limiting equilibrium prediction method, FLA3D numeri- cal simulation prediction method, and Kachugin method. The result shows that the limit- ing equilibrium prediction method and FLAC3D numerical simulation prediction method are more reliable, for it can provide the full basis for the reservoir shore＇s protection design.
