| 摘 要： | 二滩水电站库区的地层岩性，按其组合和沉积建造分为三段。大部库区位于金河－菁河断裂、雅砻江断裂与华坪－攀枝花东西向断裂所围限地区，称“共和断块”。除沿断块边界断裂有新构造活动外，断块内部相对比较稳定。电站建成蓄水后，由于库区水位提高及大量的滑坡而促使区内断裂的活动和发展。有可能诱发地震，应引起高度重视。

| Abstract: | According to rock association and sedimentary formation, strata in Ertan Hydropower Station dam area may be divided into 3 Members.A large part of the dam area lies in Gonghe fault block delimited by Jinhe-Qinghe, Yalongjiang and Huaping-Panzhihua fractures. The fault block is relatively stable except that neotectonic activity develops in the marginal area. Reservoir storage and lots of landslides will result in reservoir-induced seismisity. We should attach great importance to it. |
