摘　　要：用阻抗分析方法,对有一块开缝板和一个消浪室组成的开缝板沉箱防波堤的波浪反射系数进行系统的研究。在对开缝板消波机理分析基础上,导出一个所有参数都可计算的、完全封闭的波浪反射系数理论公式。该式物理概念明确、结构简单,与已知学者的试验成果对比,理论与试验吻合良好。This paper studies the interaction of plane wave with a slot-wall caisson breakwater,which consists of a porous front wall and a rigid impermeable backwall.Based on analysis of the wave impedance and flow resistance,analytical results of reflected wave heights are obtained.In the formula,all the parameters can be calculated.The theoretical predictions of reflection coefficients using the present model are compared with the test data of previous authors,and it is found that the results from this theory are in good agreement with experimental data.
