摘　　要：提出了一种由多层圆弧板组成的新型透空式防波堤结构,并对其在二维规则波浪作用下的消波性能进行了物理模型试验研究。在不同入射波高条件下,对圆弧板和水平板透空结构的消波性能进行了比较分析,探讨了圆弧板间距和层数对圆弧板透空式结构消波性能的影响。研究结果表明,圆弧板透空式结构的消波效果优于水平板式透空结构,在相对宽度为0.2时,可以使透射系数达0.5以下。随着圆弧板间距从0.15 m减小到0.05 m时,消波效果逐步提升,而圆弧板的层数对结构的消波性能也有一定影响。The arc-plate type breakwater,which consists of several arc plates,is proposed in this article.The wave damping performance of the breakwater is explored by two dimensional regular wave model tests.The performance of the breakwater is compared with that of the similar breakwater which consists of several horizontal plates.The reflection and transmission coefficients are presented along with the relative width.The amount and the gap of the arc plate that will influence the performance are discussed.It is demonstrated that the performance of the arc-plate type breakwater is better than that of the horizontal plate type breakwater.The transmission coefficient can be reduced to 0.5 when the relative width is about 0.2.The performance can be improved when the gap is reduced from 0.15m to 0.05m gradually.And the amount of the arc plate has a certain influence on the wave damping performance.
