【摘要】 利用混合物理论和连续介质力学的基本原理,推导了考虑质量耦合效应的流体饱和弹性孔隙介质的波动方程,并与经典的Biot波动方程进行了对比。结果表明:该文得到的方程包含了Biot波动方程的所有要素,且形式与后者基本相同。比较而言,该文推导过程具有更明确的物理意义,概念也更完整。更多还原

【Abstract】 The equations of wave propagation with mass -- coupling effect in fluid -- saturatedelastic porous media are formulated based on the theory of mixture and the basic principle of themechanics of continuum. The formulated equations are compared with the classical equations of wavepropagation presented by Biot. It is shown that the equations obtained in this article include all thebasic elements appearing in Biot equations, and they are same as the latter in the form basically.Compared with the Biot equations, the formulation process adopted to obtain the equations in thisarticle has more explicit physica1 meaning, and the concept is more complete.更多还原
