流体饱和多孔隙固体中波动方程的数值模拟

Numerical Simulation for the Wave Equations in a Fluid-satutated Porous Solid

利用Ｇａｌｅｒｋｉｎ法推导出了流体饱和多孔隙介质中波动方程的有限元方程。数值模拟的结果验证了Ｂｉｏｔ关于流体饱和多孔隙介质中存在两类纵波的预言［１］。

The finite element equations for the wave equations in fluid-satureted porous solid are got by Galerkin method.The'results of numerical simulation prove Biot's prediction that there are two dilatational waves in a fluid-saturated porous solid.
