摘要
为提升浮式防波堤的消波性能,提出一种T型浮式防波堤.首先基于数值模拟方法,建立了波浪与T型浮式防波堤作用的数值模型,然后分析了波浪作用下T型浮式防波堤的吃水深度、腹板高度和浮箱宽度分别对透射系数、锚链受力及波压力分布影响,最后结果表明在相对宽度为0.48时,防波堤腹板高度为0.35 m时的消波性能相对于无腹板可以提升76%,同时可以减小锚链拉力.
In our report, in order to improve the abilities of floating breakwater to protect coasts, harbors and marine structures from wave attacks, a novel type of T-shaped floating breakwater is proposed. Firstly, the numerical simulation method was used to establish a numerical model of the interaction between waves and T-shaped floating breakwater;Secondly, the effects of the draft depth, the height of vertical plate, and the pontoon width on the transmission coefficient, mooring force, and wave pressure distribution of T-shaped floating breakwater under waves action, were analyzed. The results indicated that when the relative width and vertical plate height of breakwater are 0.48 and 0.35 respectively, compared with that there are no vertical plate, the wave attenuation performance can be improved by 76%, and the mooring force can be reduced.
