摘要
文中主要采用Stuart Crampin提出的偏振分析技术,把数字化的地震资料进行了滤波和还原处理,对唐山地区进行了近震S波分裂的分析,得出这一地区的主压应力场方向为北东方向。
In this paper, the polarization analysis technique, proposed by prof. Stuart Cram-pin, is applied and digital seismic data is processed by filtering and transfering. The authors discuss S-wave splitting of local earthquakes occurred in Tangshan region, and give that the azimuth of main compressional stress field is north-east diretion.
