Strong ground motion is influences by factors such as the seismic source, path, and local site conditions. At present, when using the stochastic finite fault method to simulate the ground motion filed of near-field destructive earthquakes, the ground motion parameter model established based on large-scale regional observation records may encounter problems such as inconsistent parameters, uncertain simulation results, or poor simulation accuracy may arise due to the lack of consideration of the regional characteristics of the parameter model. Several aspects that still need to be further studied in near-field high-frequency ground motion simulation technique were analyzed. The research progress of seismic model parameters and the problems to be addressed were elaborated from four aspects: the geometric dimensions and slip of rupture faults, the geometric propagation and viscoelastic attenuation of ground motion, the high-frequency attenuation parameters of source spectra, and local site amplification. Based on strong-motion observation records, the statistical laws, intrinsic relationships, and interaction mechanisms of parameters in small-scale regional ground motion models are revealed, and a refined simulation method for ground motion fields is established. These laws and methods have important practical significance for evaluating the correctness of ground motion results, as well as important academic value and engineering guidance for post-disaster reconstruction and rescue, structural dynamic analysis, and seismic design. They can also provide ideas for probabilistic seismic demand analysis of structures based on scenario earthquakes.
