翼板浮式防波堤消波性能

Wave suppression performance of wing-plate floating breakwater

随着近年来海岸工程与海上作业对浮式防波堤的需求不断增加,提出了一种带翼板的新型浮式防波堤。基于三维势流理论,对翼板浮式防波堤的消波性能进行了计算分析,并与传统方箱式浮式防波堤进行对比。证明了在较长周期的波浪中,翼板浮式防波堤拥有更好的消波能力。翼板浮式防波堤截面参数对消波性能的影响表明:1)箱体宽度越大、吃水越深,防波堤消波效果越好;翼板长度越长、角度越小,最优消波效果对应的波浪周期越长。2)适当调整截面参数,可以使翼板浮式防波堤适应更多的海浪环境、增加更多的适用场景。

With the increasing demand for floating breakwaters in coastal engineering and offshore operations in recent years,we propose a new type of floating breakwater with wing plates.Based on the three-dimensional potential flow theory,we calculate and analyze the wave suppression performance of the new floating breakwater,and compared it with the common box-type floating breakwater.It is proven that the new floating breakwater has better wave suppression performance for waves of longer periods.The influence of the cross-sectional parameters of the wing plate floating breakwater on the suppression performance shows that:1)The larger the box width and the deeper the draft,the better the wave suppression performance of the new breakwater.Besides,the longer the wing plate and the smaller the angle,the longer the wave period of best wave suppression performance.2)Appropriate adjustment of the section parameters can make the floating breakwater with wing plates adapt to more wave environments and add more applicable scenarios.
