四川锅浪跷水库地震台网关键技术指标验证

The Key Technical Index Verification for the Seismological Network at the Guolangqiao Reservoir,Sichuan Province

四川省雅安市天全县锅浪跷水库地震台网在技术设计阶段,对台基噪声水平、监测震级下限(M_(L)0.5)、观测动态范围和地震活动性4个关键技术指标进行了精心的设计。锅浪跷水库台网建成后,必须对这上述指标进行验证,以此判断台网建成后能否达到技术设计的要求。通过对锅浪跷水库地震台网运行期间记录的数据和产出的地震资料进行分析,对上述4个指标进行验证,结果表明各个技术指标达到了技术设计时的要求。

In the technical design stage of the seismological network at the Guo Langqiao Reservoir in Tianquan County,Ya'an city,Sichuan Province,we carefully designed four key technical indexes including station noise,earthquake magnitude limit(M_(L)0.5),observation dynamic ranges,and seismic activity.When the network is completed,the aforementioned indexes must be verified to estimate whether the network could meet the requirements of technical design.Some seismic events were recorded during the construction of the seismological network.The results show that each technical index meets the requirements for the technical design,which ensures the monitoring quality.Therefore,the seismological network at the Guo Langqiao Reservoir has been well built for future operation.
