近些年来,作者参加了瀑布沟水电站区域构造稳定性调查,本文仅就瀑布沟水电站有关的断裂构造形变进行了研究和剖析。不当之处,请指正。一、断裂构造特点瀑布沟水电站位于大渡河中游,区域地质基础比较复杂,大地构造上属川滇南北构造带北段东缘缓冲地区,其外围断裂构造的展布有南北向、北西向、北东向、东西向及北北西 In recent years, the author participated in the investigation of regional structural stability of Pubugou Hydropower Station. In this paper, only the fracture structure deformation related to Pubugou Hydropower Station has been studied and analyzed. Improper, please correct me. First, the characteristics of fault structure Pubugou hydropower station is located in the middle reaches of Dadu River, the regional geological foundation is complex, the earth structure belongs to the northern edge of Sichuan-Yunnan North-South structural belt buffer zone, the distribution of its peripheral fault structure north-south, northwest, north East, East and West and north and west
