Abstract:A more reasonable seismic medium model and a spatial correction template are put forward so as to solve the problems in hypotheses of uniform medium or continuous medium. Layered medium can be modpled using the average velocity curve and horizontal layered medium, and its layer number should be decided according to practical conditions and accuracy reQuirement, Expression v(z)=v0(1+βz) is not very satisfactory for modeling a continuous medium, so a more reasonable velocity expression must be chosen on the basis of true velocity,Generally speaking, expression v(z)=v0 (1+βz)1/n,is more generalized, the calculation for n=2 being made in the paper. The design of spatial correction template is recommended in the paper.
