Abstract
Generally speaking, the factors of both medium and tectonic that give rise to heterogeneity of the earth crust and mantle structures should be taken into account simultaneously in three-dimensional seismic ray tracing. In this paper, the three-dimensional structure models are constructed with the model similar to generation system in computer-aid design and manufacturing (CAD/CAM). Based on the algorithm proposed by Cerveny et al. for complete seismic ray tracing in complex three-dimensional structures, a new technique called the indirect-approach method for two-point seismic ray tracing in three-dimensional laterally heterogeneous media has been put forward, and its numerical computing examples were given.
