| 摘 要： | 利用山西数字测震台网“十五”数字化之后34次 ML2.5～ML5.2级地震波形资料,采用Atkinson方法反演出非弹性衰减Q值随频率f的关系为Q( f)=469.5df0.3141；采用Moya方法反演得出41个台站的场地响应,结果显示出仪器安置在山洞且地处外界干扰小的台站没有明显的放大效应,而其它台站尽管都是基岩台...

| Abstract: | Based on waveform data of 34 ML2.5-ML5.2 earthquakes from Shanxi digital seismic network, the relationship between inelastic attenuation Q value and frequency f are inversed using Atkinson method, which is Q（f）=469.5 f^0. 3141 Site response of 41 seismic stations are calculated through the Moya method. The results shows that stations installed in cave do not show obvious site amplification effect, all the other stations, although installed on bedrock, show site amplification effect in varying degree. Source parameters of the 34 earthquakes are calculated using Brune method; Relationships between ML magnitude and seismic moment, ML magnitude and stress drop, ML magnitude and moment magnitude are also studied. |
