三峡水库诱发地震监测简介

Introduction on monitoring system of earthquakes induced by Sanxia Reservoir

长江三峡工程是举世瞩目的特大型水利枢纽工程。它的建设将对三峡库区及其周边环境产生巨大影响 ,水库诱发地震就是可能产生的众多影响之一。中国长江三峡工程开发总公司为了三峡水库周边及其下游的防震减灾需要 ,投资建设了“长江三峡工程诱发地震监测系统”。三峡数字遥测地震台网是该系统中的重要组成部分 ,担负了水库诱发地震活动的日常监测任务。本文从水库诱发地震问题出发 ,简要介绍了该台网的设计思路、布局、监测能力和技术系统。

Sanxia reservoir is a great projection in the world.The construction of this dam will affect the surroundings of the reservoir dam greatly.Induced earthquake is one of effects caused by reservoir.In order to monitor the seismic activity around the reservoir,a monitoring system of earthquake was set up by the Changjiang River Development Cooperation.The Sanxia telemetering digital seismic network is a main element of this monitoring system.It monitors the earthquakes daily induced by the reservoir.We introduce here the design thoughts,sub stations distribution,monitoring abilities and technical systems on this monitoring system.
