摘　　要：利用大岗山水库地震监测台网,在大岗山库区建立了主动震源探测系统。主动震源设备为10t精密控制机械震源,接收台站包括大岗山水库地震台网的8个固定台站、2个加密流动台站和1个震源接收台。本文介绍了大岗山库区主动震源探测系统的基本情况、震源与地基的耦合特征、系统的性能及其影响因素等,并通过初步数据处理获取了大岗山库区地壳波速的相对变化。Based on the seismic monitoring network of the Dagangshan Reservoir,we established a detection system of active seismic source,including an Accurately-Controlled Routinely-Operated Seismic Source which weighs 10 tons,as well as 8 permanent stations,2 mobile stations and 1 source receiver station.In this paper,we introduce the basic information of the detection system,the source-groundsill coupling,the performance and its affecting factors.Also,the relative velocity variation in the Dagangshan reservoir area is obtained through the preliminary data processing.
