    • Abstract
  • In order to study the influence of complicated geological conditions on frequency dispersion curves of Rayleigh surface wave, the paper, using finite difference seismic numeric modeling, carried out forward modeling on three models, obtained wave field snapshot and single shot record at certain time.Analysis of frequency dispersion of modeled record showed that there was no frequency dispersion in single layer homogeneous medium, phase velocity of frequency dispersion curves in double layer homogeneous media on relief surface was only related to the parameters of media themselves, and was not influenced by topography, in media with interbedded soft layer in flat surface, frequency dispersion of Rayleigh wave was very evident.
