| 摘 要： | 金安桥水库区按地质构造、岩性、区域应力场、地震活动背景及水文地质条件,可分为3个库段。从坝址区到果世库段的岩性为玄武岩,主要断裂有三古断裂、楚夺洛断裂、树底断裂。在坝址到果世库段的树底和果世附近,果世至排卖当碳酸盐岩库段的瓦金坪、黄洋沟附近有发生5.0级地震的可能,震中烈度可达Ⅶ度。排卖当至库尾的碎屑岩库段不会发生水库诱发地震,其中碎屑岩中夹的碳酸盐岩段有发生3.0地震的可能性,烈度<Ⅵ度

| Abstract: | Basing on geological field investigation and other relevant data, this paper analyzes the geologic tectonic features, seismic activity background, regional stress field and hydrogeologic conditions of the Jinanqiao reservoir area. Moreover, the comparison with the other reservoirs of the similar conditions has been carried out. The results indicate that induced earthquake is possible to occur in the Jinanqiao Reservoir of the Jinshajiang River. The bedrock in the dam site to Guoshi segment of the reservoi |
