| 摘 要： | The velocity-stress finite-difference method is adopted to simulate the elastic wave propa-gation in azimuthal anisotropic media.The difference grids are completely staggered in the numerical im-plementation.To reduce the computational work,the absorbin8 boundary conditions for anisotropic mediaare introduced first and the corner points are specially treated.Examples show that more accurate resultscan be obtained from the modeling algorithm,which cost much less computational time than the conven-tional methods.Therefore,the algorithm has broad application prospects in engineering.
