丹江口水库诱发地震基础数据库建设
|
摘要
丹江口水库是南水北调中线工程的源头,其地震研究工作始于勘测设计初期阶段。水库初期工程建成、蓄水后,库区地震活动加强。并且,续建工程的蓄水位提高后,有可能诱发新的地震。所以,有必要对丹江口水库诱发地震数据建立基础数据库,为水库续建工程的地震预测,库区的防灾和减灾服务。丹江口水库诱发地震基础数据库是以地理信息系统Mapinfo为平台构建的,属于可视化的数据库系统。数据库包括基础地理信息、地质环境信息、水位与库容信息、地震监测信息、地震活动信息。
The seismic research of Dandjiangkou reservoir, which is the headstream for south-to-north water diversion project,began in the initial phase of reconnaissance design.The seismic activity enhanced in the reservoir area after impoundment in the initial project.The seismicity possibly induced in the subsequent project after the water level rises.So it is necessary to establish the database of Danjiangkou reservoir induced seismicity which will be applied to the prediction of seismicity,the quakeproof and reducing disaster of reservoir area.The database was developed based on the Geography information system-Mapinfo. It belongs to visual database system,which includes basic geographical information,geographical environment information,water level and volume of reservoir information,seismic monitoring information and seismic activity information.
