摘　　要：南水北调中线水源工程大坝加高后,丹江口库区内的部分库段在库水作用下易发生坍岸问题。为了预测水库坍岸范围和发生坍岸的难易程度,对丹江口水库的地形、地质条件和坍岸的影响因素和型式进行了分析。在此基础上,通过大量的调查,采取工程地质类比法预测了坍岸范围和难易程度,为对坍岸范围内的对象采取针对性的处理措施提供了地质依据。After heightenning dam of the middle-route water sources project of south-to-north water transfers,it is important to survey all material objects in the influential area in order to predict the area and difficulty degrees of bank caving. This paper briefly describes topography and geology conditions of the Danjiangkou reservoir,and analyses the influential factors and forms of bank caving,and adopts engineering geologic analogy method to predict the influential area and difficulty degrees of bank caving on the basis of wide investigation. Moreover, it provides geologic bases for dealing with all material objects in the bank caving＇s area pertinently.
