| 摘 要： | 本文应用构造解析法——断层滑动矢量分析,通过Etchecopar电算法定量反演了唐山地区平均构造应力场。结果表明:唐山地区平均构造应力场可分为三期,第Ⅰ期为南北—北西向的挤压(中生代以前);第Ⅱ期为北东东向的挤压(始新世—更新世早期);第Ⅲ期为北东向的挤压(更新世中期以后)。第四纪构造应力场的变化是一次重要的构造事件。

Journal of Seismology INVERSION FOR THE AVERAGE TECTONIC STRESS FIELD IN TANGSHAN AREA BY FAULT SLIP VECTOR METHOD |
| |
| Abstract: | In this paper, an up-to-date tectonic analytical method the fault slip vector analysis is applied in the inversion for the average tectonic stress field in Tangshan area with Etchecopar computer procedure. The result shows that the average tectonic stress field in Tangshang area can be divided into three periods: 1. NS-NW extruding(before Mesozoic); 2. NEE extruding(Eocene to early Pleistocene); 3. NE extruding (after midio Pleistocene). The change of the tectonic stress field of Quaternary is a significant tectonic event. |
