摘　　要：针对实际工程中的可透浪式斜坡式防波堤结构,在不考虑越浪的情况下,通过物理模型和数值模拟试验相结合的方法,对斜坡式防波堤的透浪特性进行了分析研究,讨论了斜坡式防波堤透浪系数与堤心石粒径、相对堤身宽度等堤身参数以及透浪系数与入射波高、入射波周期和波陡等入射波波要素之间的关系,根据试验结果分别提出了规则波和不规则波作用下不越浪斜坡式防波堤的透浪系数半经验半理论公式。验证结果表明,计算结果与试验结果拟合效果较好,可应用于可透浪斜坡式防波堤透浪系数的估算。In view of the permeable sloping breakwaters in the practical engineering,wave transmission characteristics of the sloping breakwater were analyzed without considering the overtopping,by using the combined methods of physical experiments and numerical simulations.The relationship between the wave transmission coefficient of sloping breakwater and multiple wave parameters for breakwater and incident wave were mainly discussed,including the particle size of core material and relative dike width of breakwater body as well as the wave height,wave period,and wave steepness of incident waves.The semi-empirical formulas of wave transmission coefficient under regular wave and irregular wave actions for a sloping breakwater were fitted,respectively.Good agreement between the calculated results and the experiment results was achieved,which demonstrates that the proposed formulas can estimate the wave transmission coefficient of permeable sloping breakwater.
