| 摘 要： | 为了研究瑞雷面波在复杂地质条件下的传播规律和波场特征,采用交错网格高阶有限差分方法对浅层各向同性弹性介质进行了包括瑞雷面波和体波在内的全波场模拟.通过均匀半空间模型和层状介质模型的模拟,验证了含有瑞雷面波的全波场理论的正确性.

| Abstract: | In order to research the wave-field propagation and characteristic of the Rayleigh wave in the complex geological conditions.The method of high order staggered grids finite difference is applied in the wave field simulation of the shallow isotropic elastic medium including the Rayleigh wave and body waves.By the simulation of homogenous half space model and layered media model,simulations indicate the correctness of the wave field theory record including Rayleigh wave.It provides an effective additional method of high mode of Rayleigh wave inversion and application. |
