我们结合搜寻程序和最优化程序,对平均应力张量进行反演,并使用 P波初动节面解的资料,将这种方法应用于地壳应力场的研究。通过分析海城、唐山、邢台、安阳、溧阳、台湾、福建和广东的资料,我们获得了中国东部地壳应力场的特征:主压应力方向总是具有小倾角,但方位角不同,从 ENE (中国东部北区)到 ESE(中国东部南区)。这种图象可能与太平洋板块西北部沿东北东和菲律宾板块沿东南东方向的会聚有关。 We combine the search program and the optimization program to invert the average stress tensor and use the data of the initial solution of the P wave to solve this problem. This method is applied to the crustal stress field research. By analyzing the data of Haicheng, Tangshan, Xingtai, Anyang, Liyang, Taiwan, Fujian and Guangdong, we obtain the crustal stress field characteristics of eastern China: the principal compressive stress direction always has a small dip angle but different azimuth angles, East China North) to ESE (South East China). This image may be related to the convergence of northwestern Pacific plate along northeast and east Philippines along the Philippines plate.
