| 摘 要： | 利用2009—2015年河北地震台网记录的156条地震波形数据,基于Atkinson方法,计算河北地区非弹性衰减系数随频率的幂函数,求得Q值。采用Moya方法,反演得到144个地震台站的场地响应。将地震台按台基类型分为5类进行分析,结果显示,各类台基地震台场地响应随频率变化特征差异明显。

| Abstract: | By using the 156 seismic waveform data recorded by the Hebei seismic network from 2009 to 2015, and based on genetic algorithm, the Atkinson method is used to calculate the power function of the non elastic attenuation coefficient with frequency in Hebei area. The site response of 144 stations is obtained by Moya method. The base station of different types are divided into five categories. The results show that there are obvious differences in response with changes of frequency to various base station sites. |
