摘    要:本文回顾了已有的关于透空式防波堤的波浪透射率的理论计算方法,分析了多层挡板桩基透空式防波堤的消浪机理。结合防波堤断面波浪试验,探讨多层挡板桩基透空式防波堤的消浪特性。研究结果表明多层挡板桩基透空式防波堤能够显著消减波浪,它的应用突破了透空式防波堤仅适用于小尺度风浪水域的经验。研究发现影响防波堤消浪效果的因素中,挡板的透空率和设置方式的影响最为显著。文中提出的减小波浪透射率的方法可供设计部门参考。

关 键 词:透空式防波堤  消浪特性  波浪透射率

Abstract:The existing theoretical methods to calculate the wave transmission ratio are reviewed. The dissipation mechanism is analysed for wave passing through pile foundation tier retainer breakwaters. Characteristics of wave dissipation for pile foundation tier retainer breakwaters are detected by wave experiments. It is shown that pile foundation tier retainer breakwaters have a good wave dissipation effect, and this kind of breakwaters could be constructed in the relative rough wave conditions. Mang elements are found to have influence on the wave dissipation rates, and the influence of the porosity and the arrangement of retainers is the most pronounced. The present ways to decrease the wave transmission ratio offer a basis for the structure design of pile foundation tier-retainer breakwaters.
Keywords:open  type  breakwater  characteristics of wave dissipation  wave transmission ratio
