| 摘 要： | 利用陕西省测震台网的25个台站和2008—2010年所记录到的19个地震进行了陕西省Q值及台站场地响应值的计算,得出非弹性衰减Q值随频率f的关系为Q（f）=826.57f 0.3538。这说明陕西省处于高Q值区域,地壳相对较稳定,地震活动性相对较弱。计算得到的陕西省数字测震台网25个台站的场地响应值,其中,只有铜川台（...

| Abstract: | Based on 25 stations of Shaanxi seismic network and 19 earthquakes recorded between 2008 and 2010, Q -value and site response values of each seismic station are calculated. The results show that the relationship between frequency f and inelastic attenuation Q -value is Q （f） = 826.57f0.353 8, which indicates that the province is a high Q - value area with a relatively stable crust and weak seismic activity. Most of the site response values of the 25 stations exhibit no significant amplification effect except that of Tongchuan station in 2 -8 Hz, Suide station in 12 - 17 Hz, and Huaxian Station in 6 -20 Hz. |
