摘要

根据台网布局和实际获得的参数 ,运用反推方法 ,对山西数字遥测地震台网和模拟遥测地震台网的监控能力进行了对比分析 ,粗定了数字遥测地震台网速报责任区的范围 ,并对数字遥测地震台网的大震响应能力进行了讨论。依据数字化台网的两期改造方案 ,估算了其监控能力。结果表明 ,目前山西数字遥测地震台网中部和南部的台站密度明显不够 ,北部监控能力为 1 .8级 ,中部监控能力为 2 .3级 ,南部监控能力为 2 .5级。山西数字遥测地震台网对网内大震参数的测定能力为 6.6级。
Based on the station distribution of the network and obtained parameters, the analysis of earthquake monitoring capacity of the Digital Seismic Network of Shanxi province, compared with analog one, is made. The ranges that earthquake location can be made quickly by using the Digital Seismic Network of Shanxi Province are evaluated and the maximum earthquake magnitude that the network can determine is discussed. The earthquake monitoring capacities for each of two stages of the Digital Seismic Network of Shanxi Province as the upgrading plan are estimated. The result shows that the number of stations installed in middle and southern part of the Digital Seismic Network of Shanxi is not enough to have a reasonable earthquake monitoring capacity. The earthquake monitoring capacity in the northern part of Shanxi province is [WT6BX]M=1 8, M=2 3[WT6BZ] in the middle part and [WT6BX]M[WT6BZ]=2.5 in the southern part. For the earthquakes occurred within the network, the largest magnitude that can be determined by the Digital Seismic Network of Shanxi Province is [WT6BX]M[WT6BZ]=6 6.
