福建台网共建有88个速度型观测台站,利用这些台站记录的50个地震波形资料,用Atkinson方法反演了福建地区的非弹性衰减,其非弹性衰减Q(f)=483.6f~(0.352),这与福建地区构造活动较为稳定,介质的均匀程度相对较高,对频率的依赖较少的理论相符.用Moya方法计算台站的场地响应,大部分台站在1~2附近波动,说明其台基良好;部分台站在高频部分出现放大效应,说明台基存在一定的风化;部分台站则在高频出现衰减,说明台基存在一定的松软沉积层.经过本文的研究,为下一步福建台网产出地震的震源参数建立数据基础,丰富了福建台网的数据服务内容.对震级校正、台站场地选点及评价、地震工程和灾害评估有一定的参考意义.
A total of 88 velocity-type observation stations were built in Fujian Province. Using the 50 seismic waveform data recorded by these stations, the inelastic attenuation of Fujian Province was inverted by Atkinson method. The inelastic attenuation Q (f) = 483.6f ~ (0.352), which is consistent with the tectonic activity in Fujian area, the relatively homogeneous medium and the less dependent on the frequency.The Moya method is used to calculate the site response of the station, most of the stations are between 1 and 2 Which shows that there is a certain degree of attenuation in the high frequency of some stations, which indicates that there is some weathered sediments in some stations. At some stations, attenuation occurs at high frequencies, indicating that there is some soft sediment in the stations. , Which establishes the data foundation for the hypocenter parameters of the next Fujian-Taiwan network seismic output and enriches the data service contents of Fujian station network.It has certain reference to the correction of magnitude, site selection and evaluation of stations, earthquake engineering and disaster assessment significance.
