从向家坝水电站工程地质勘察中揭露的大量裂缝出发，运用近年来国内外发展起来的年龄测试技术对裂缝充填物进行了绝对年龄测定，并结合河段的地质特点。新构造运动特征，对岸坡裂缝进行了类型划分，并探讨不同的成因机制。
Based on a large number of cracks revealed in the engineering geological survey of Xiangjiaba Hydropower Station, the authors used the age test technique developed in recent years to determine the age of fracture fillings and to analyze the geological characteristics of the river sections. Neotectonic movement features, the type of slope cracks on the bank division, and explore different genetic mechanism.
