该文从渗流理论基本方程出发,用渗流力和附加惯性力表示体积力项,导出了水波在孔隙介质中传播的方程。根据非定常渗流原理,修正孔隙介质中水波的自由表面条件,由此得到一个新的色散方程。为了简捷,用阻抗方法导出波浪从孔隙堤上反射和传递系数公式。所得公式与现有的理论分析成果及试验结果均吻合较好。 Based on the basic equations of seepage theory, the paper expresses the volume force term by seepage force and additional inertial force, and derives the equation of water wave propagation in porous media. According to the unsteady seepage principle, the free surface condition of the water wave in the pore medium is modified, and a new dispersion equation is obtained. For simplicity, the impedance method is used to derive the formula for reflection and transfer of the wave from the dike. The obtained formula is consistent with the existing theoretical analysis and experimental results.
