Rough topography is very common and we have to deal with it during the acquisition, processing, and interpretation of seismic data. Modeling of seismic-wave propagation in medium with irregular topography is beneficial to process and interpret seismic data acquired by active and passive source seismology conducted in areas of interest such as mountain ranges and basins. Seismic wavefield and seismic wave traveltime field are two important ways to describe seismic wave propagation. In this paper, we try to give a basic review on the research progress of seismic wave propagation simulation method through the above two aspects, and show some new research results in this field, in the meaning of supplying a initial material so as to enable readers get some basic knowledge of the development obtained in the past and current, and find some breakthroughs then may make some contributions to the development or applications of new methods and technologies themselves. |
