摘要: 本文提出了一种解流体饱和多孔隙介质中波传播方程的数值方法,并详细推导了该方法的计算公式.用此公式对单界面模型中地震波的传播进行了模拟,结果与Biot理论预测的相符。

Abstract:

In this paper, we provide a numerical method for the solution of elastic wave equations in fluid-saturated porous media, and derive its calculation formula. Using thes formula, we simulate the wave propagation in a fluid-saturated media model with one reflection plane,the result of which is corresponding to Biot's theoretical prediction.
