摘要

在某工程的区域稳定性研究和水库区工程地质调查的基础上,综合分析了水库的区域地震地质条件。依据实际存在的诱发地震条件组合,对该水库诱发地震的环境进行了分区评价。重点研究了水库区地质背景、水库诱发地震的关键因素及水库诱发地震的潜在危险性预测等方面。研究表明水库在运行过程中有发生裂隙断块岩体型或裂隙喀斯特岩体型诱发地震的可能性,但诱发地震强度仅为微震或弱震,其基本烈度不会超过历史构造地震对区内的影响。
Earthquakes occur frequently under the complex quake geological condition in China,and they did occur during the time of reservoir filling.Until now 25 cases were recorded.Therefore China is one of the countries that earthquakes occur frequently due to reservoir filling.Based on the areal stability research and geological investigation of reservoir,the areal seism geological condition was analyzed synthetically.This paper evaluated the environment of earthquake occurring and the reservoir district geological background.The results suggest there is the feasibility that the earthquake occurs due to 2 kinds of reasons when the reservoir is in the store process: one is that fractured rockmass in flaw,the other is karst rockmass with flaw.
