根据“八五”期间邢台地震区深部地球物理方法的综合探测研究成果，依据P波、S波联合解释和二维密度反演，并结合浅部构造和三维应力场数值模拟计算等资料，进行综合分析研究。以1966年邢台6．8级地震为例，揭示了邢台地震区的孕震发震过程。邢台地震区的深部结构和介质结构：①中、下地壳内分布有北东向高角度深断裂，深断裂两侧出现明显的波速比异常。②中地壳有低速高导层和密度不均匀异常。③上地壳底部有滑脱构造带，浅部为束鹿断凹。
According to the comprehensive exploration results of deep geophysical methods in Xingtai earthquake area during the Eighth Five-Year Plan, based on the joint interpretation of P-wave and S-wave and the two-dimensional density inversion, combined with the calculation of shallow structure and 3D stress field, Comprehensive analysis and research. Taking the earthquake of magnitude 8.6 in Xingtai in 1966 as an example, the seismogenic process of Xingtai earthquake area was revealed. The deep structure and medium structure of Xingtai earthquake area: (1) North-east high-angle deep faults are distributed in the middle and lower crust; obvious anomalous wave velocity ratio appears on both sides of the deep fault. ② The middle crust has a low-velocity and high-conductivity layer and anomalously uneven density. ③ There is a slip-tectonic belt at the bottom of the upper crust, and the shallow part is the deer break.
