摘要
根据浙江数字地震台网记录的发生在浙江省及其附近海域的中小地震的波形资料,采用互相衔接的三段几何衰减模型,利用遗传算法联合计算,通过在频率域内的分析,测定和研究了浙江地区剪切波的几何衰减和非弹性衰减以及场地响应的特征。
Based on waveform data of moderate and small earthquakes, occurred in Zhejiang Province and adjacent sea area and recorded by Zhejiang Digital Seismic Network, using three segment continuous geometry attenuation model and gene algorithm for combined calculation, the geometry and non-elastic attenuation of shear wave and the characteristics of site response in Zhejiang area are studied and determined in frequency domain.
