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.
Key words: ocean engineering; transmission coefficient; submerged breakwater; sloping bed
