Abstract: In this paper considering different viewpoints of seismogenic structures of Tangshan earthquake, the seismogenic mode of Tangshan earthquake has been studied using the finite element method. The characteristics of Tangshan earthquake are also described,A preliminary discussion has been made on identifying the earthquake risk areas on the basis of both regional stress direction and condition of stress release.

摘要： 本文考虑了对唐山地震发震构造的不同看法,利用有限单元法分析了唐山地震的发震构造模式,解释了唐山地震的特点。从区域应力方向和应力释放条件上对如何判定地震危险区的问题进行了探讨。
