摘　　要：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。From the foundational permeable equations, the body force is represented by permeable and inertia forces, wave equation in the porous structures is obtained. We provide a new dispersion relation on the base of unsteady seepage and free surface condition. The reflection and transmission coefficients of water wave from porous breakwater are obtained by using impendence method. The results predicted by present formulas agree well with theoretical results and test data in open literatures.
