| 摘 要： | 潜堤是防止海岸侵蚀的常用护岸建筑物,准确的掌握潜堤前后波浪的传播变形规律十分必要.该文以斜坡上梯形潜堤为研究对象,基于波浪水槽实验,通过谱分析探求线性波、非线性波、非规则波通过斜坡上潜堤内部组成能量的变化规律,分析相同的入射波情况下波浪倍频能量演变与堤顶水深大小的关系,得出堤顶水深越小主频能量衰减越大的规律.同时,比较研究线性波与非线性波作用下潜堤前后波能的变化,发现非线性波高倍频能量产生更加剧烈.

| Abstract: | Submerged breakwaters have become increasingly popular due to their multiple functions, which are to protect shoreline or harbor and to prevent beach erosion in the coastal zones. In this paper submerged breakwater in the coastal zones was modeled in a wave flume. The experiment was outfitted with a servo-hydraulically actuated wave-maker at one end and a sloping bottom (slope=1:20) at other end for modeling water motion in the coastal region. Wave elevation measurements were made by using capacitance-type ... |
