摘要

本文利用唐山地区强震观测台网在过去几年中记录到的强震数据,采用震源,传播路径和局部场地效应分离方法和非线性曲线拟合技术,模拟了唐山地区的震源参数,计算了唐山地区的绝对局部场地效应。
A seismic observation array was deployed in Tangshan China. About sixty events in the range of magnitude from 2.2 to 5.9 were recorded in the past several years. By using the data of 10 events recorded at 8 stations the authors estimated the source parameters of a point source model by nonlinear curve-fitting technique for the observed S-wave displacement spectra and calculated the absolute local site effects in Tangshan area.
