摘　　要：白鹤滩、乌东德水电站为金沙江下游四级水电开发中的前两级电站,为西部大开发战略中的重点水电工程。白鹤滩、乌东德水库地震监测台网为水电站正常蓄水发电的重要基础保障工程,验证运行几年后的台网监测能力是否依然满足设计要求,能进一步确认台网运行质量是否稳定可靠。通过对监测台站实测的台基噪声进行计算分析,并用监测到的地震进行验证。结果表明:白鹤滩、乌东德水库地震监测台网的监测能力在水库影响区内达到M_(L)0.5的设计要求,运行质量稳定。The Baihetan and Wudongde Hydropower Stations belong to the first two stages during the four-stage de-velopment of hydropower in the lower reaches of the Jinsha River,which are the key hydropower projects in the Western Development Strategy.The seismic monitoring network of the Baihetan and Wudongde reservoirs is an im-portant basic guarantee project for the normal impoundment and power generation of the hydropower stations.We need check whether the background network monitoring capability meets the design requirements after several years of operation.And then we need confirm whether the network operation quality is stable and reliable.The actual measured platform noise at the reservoir seismic station was calculated and analyzed,which was verified by the mo-nitored earthquakes.The results showed that the monitoring capability of the Baihetan and Wudongde reservoir seis-mic networks could meet the design requirement of M_(L)0.5 within the influence area of the reservoir.
