青海地区S波非弹性衰减Q值、场地响应特征研究
S wave inelastic attenuation and site response in Qinghai area
摘要
Abstract
According to the geological structure the distribution of observation network,Qinghai area was divided into three subregions,including Qaidam Basin,the northeastern and southeastern of Qinghai. Based on the 112 digital seismic waveforms data recorded by Qinghai network,the inelastic attenuation Q value with frequency of these subregions are inversed by Atkinson’s genetic algorithm,showing that the Q value of Qaidam Basin is maximum while the southeastern is minimum. Site responses of 24 stations in these subregions are inversed using the Moya method, the results indicate that site responses of 15 stations are uneven in frequency domain,the others have better stability,and as a standard station,GOM station has better observation conditions, making the site responses has no magnification nearly in frequency domain.关键词
