【摘要】 根据Aki的单次散射尾波理论,利用小浪底水库地震台网短周期仪器记录的地震波形资料,估测了小浪底水库地区的尾波Qc值,Qc=(89.2±28.78)f0.913 1±0.154 3。结果表明,小浪底库区Qc值与频率有很强的依赖关系,尾波Qc值较小。参照国内相关研究成果,结合本区区域尾波Qc值数值特征认为:本研究区构造活动复杂,地震活动水平高,应加强地震监测工作。更多还原

【Abstract】 According to Aki’s single-scattering theory of coda,the coda Qc value,which is(89.2 ± 28.78)f 0.913 1 ± 0.154 3 in the Xiaolangdi reservoir area is estimated by use of the seismic waveform data recorded by short-period instruments from Xiaolangdi Reservoir Seismic Network.The results show that threre is a strong dependence between Qc value and frequency in the Xiaolangdi reservoir area and coda Qc value is small.Refering the domestic research results,combined with the numerical characteristics of coda Qc in this area,it is found that the tectonic activity is complex and the seismic activity level is high in the studied area,so the earthquake monitoring should be strengthened.更多还原
