【摘要】 运用山西地震台网的27条数字地震波形资料,基于遗传算法,用Atkinson方法得到山西地区的品质因子Q值随频率的关系。采用Moya方法反演地震的台站场地响应,40个台站的场地响应均表现为与频率有关,其中27个台站的场地响应在频率域不平坦,只有部分台站的场地响应基本没有放大,在1附近,主要是由于这些台站的仪器安放于干扰较小的山洞所致。更多还原

【Abstract】 Based on the 27 digital seismic waveforms data from Shanxi seismic network,the quality factor Q with frequency of Shanxi region are inversed by Atkinson’s genetic algorithm.Site responses of 40 stations are inversed by Moya method.Site response of all stations are frequency related.Among which,site responses of 27 stations are uneven in frequency domain.Only a number of the stations almost have no site magnification,due to their quiet instrument environments in caves.更多还原
