| 摘 要： | 潜堤是防止海岸侵蚀常用的护岸建筑物，透射系数是评价潜堤消浪效果的指标。在波浪水槽实验的基础上，提出斜坡上潜堤透射系数的定义，分析研究在线性波和椭圆余弦波作用下，斜坡上潜堤透射系数与相对堤顶水深R/Hi，潜堤的相对高程R/d以及相对位置X/L的关系。研究表明：相对堤顶水深是影响斜坡上潜堤透射系数最重要的因素，透射系数随着相对堤顶水深的增大而增大。旨在更好地评价近岸海区潜堤的消波效果，为防止海岸侵蚀提供科学依据。 |

| Abstract： | Submerged breakwaters are useful structures for mitigating coastal erosion. Transmission coefficient is a main parameter used to describe the efficiency of submerged breakwater to protect the seaward area from wave actions. The transmission coefficient of waves over submerged breakwater positioned on a slope was defined, and its variations with relative water depth over the breakwater, relative depth of submergence, relative location of submergence for the submerged breakwater under a linear wave and a cnoidal wave were analysed. The results revealed that relative depth of submergence is the most important factor in affecting the transmission coefficient, and the transmission coefficient increases with its increasing. |
