Abstract:: Based on the stochastic finite fault model of the dynamic corner frequency,we take the meizoseismal area of the Tangshan earthquake in 1976 as the research goal.The calculation model of the target zone is established and the parameters of the source model are determined by summarizing the research results of predecessors.The local site amplification is obtained by using the quarter-wavelength method based on the site condition data and soil dynamics parameters.The simulation results of the near-field strong ground motion field of the Tangshan earthquake are obtained by using the stochastic finite fault model ground motion simulation method.The results show that the ranges of VIII,IX degree simulated are similar to macro intensity comparing with the macroscopic intensity of historical earthquakes.
