| 英文摘要 | Perfectly matched layer (PML) absorbing boundary has been widely used in seismic simulation. At grazing incidence and low frequency, the classical split PML (SPML) method and the traditional nonsplit PML (NPML) method suffer from large spurious reflections. An unsplit convolutional PML. (CPML) not only fixes the disadvantages of conventional PML, but also needs less memory, computes efficiently and is easy to program. In this paper, this CPML absorbing boundary is imported to the rotated grid finite-difference method, in velocity-stress formulation, of poroelastic media. The numerical analysis of parameters in the PML absorbing boundary gives a set of optimum parameters. Numerical test shows that the CPML absorbing boundary gives a better result than the conventional PML absorbing boundary. |
