The paper summarizes the application and development of finite element numerical simulation methods in the seismo-geological study in North China in the last 30 years, and the discussion is focused on the following three aspects: the finite element model for North China, actual data used in the simulation and numerical simulation results. The study of finite element numerical simulation in North China began in 1980,since then,it has experienced the phases of development from elastic to elasto-plastic,viscoelastic and creep simulations,from 2D to 3D,from linear to nonlinear,from continuous deformation to discontinuous deformation, and from the use of individual data to the use of multiple synthetic data. It shows that finite element numerical simulation is an effective means for studying seismology and geology in North China,and distinguished results have been achieved by using simulation methods. The achievement will be the foundation for the future simulation study in North China. The paper also discusses the significance, existing problems and development tendency of finite element numerical simulation in seismo-geology in North China.
