摘要
水库地震是人类开发水力资源的工程活动中,有些水库蓄水后会出现诱发的地震现象。乌江渡水电站,是我国在岩溶地区建成的一座高原峡谷型的高坝大型水库,库区蓄水后5个月就有频繁的地震活动,主要有三个震区,至今延续时间已达13年,目前的这种地震活动势态仍在继续。本文就水电站工程及地质背景、震情与震害、地震活动的主要特征及成因机制等进行一些分析和探讨。水库地震是当今主要环境工程地质问题之一,具有研究的现实意义。
The reservoir of Wujiangdu (Wujiang River Ferry) hydroelectric power station is a large plateau-canyon-type one with a high dam in karst area. Being stored with water 5 months later, earthquake which is present in three areas has been occurring, for 13 years and still continues up to now. Some questions about engineering of the hydroelectric power station and its geological setting,the earthquake and its catastrophes,and the principal feature of seismic activity and its genesis mechanism were discussed in this paper.
