| 摘 要： | 根据山东数字地震台网7个地震台的118条波形资料，采用Atkinson方法（1992），研究了胶东地区的非弹性衰减系数；采用Moya方法（2000），研究了各台的场地响应。得到胶东地区非弹性衰减Q值随频率，的关系为Q（f）=249×f^0.596；得到的7个台站的场地响应均没有显示出明显的放大效应，这与胶东地区台站均处于岩石地基相符。

| Abstract: | Bsed on 118 horizontal-component digital seismograms recorded at 7 seismic stations in Shandong Digital Seismograph Network, and with the methods of Atkinson （1992）, the of inelastic attenuation coefficient in Jiaodong region is studied. By the methods of Moya （2000）, the site response of each station is obtained. The frequency-dependent of inelastic attenuation coefficient Q is estimated as Q（f）=249×f^0.596 the site response of 7 seismic stations do not show significant Amplification, which is consistent with their basement on rock. |
