摘　　要：针对传统透空式防波堤消浪性能存在的局限性问题,提出一种基于密排斜桩的低透空率桩基防波堤,采用桩侧设置肋板及桩位前后轴线交叉布置的方式,实现迎浪面的全遮挡。以某陆岛交通码头工程为例,对密排斜桩结构受力特点进行分析,对密排斜桩本体、肋板、吊耳及上部结构连接等设计细节进行研究,并提出对应的解决方案。结果表明,该型防波堤透射系数可降低至0.2以下,适用于波高较大、周期较长的波浪环境。For the limitations of the wave dissipation performance of traditional permeable breakwaters,we innovatively propose a pile foundation breakwater with low permeability based on closely spaced battered piles.It realizes full shielding of the wave face by setting rib plates on the pile side and crossing the front and rear axes of the pile positions.We analyze the stress characteristics of a closely spaced battered pile structure base on a land-island traffic wharf project.Then we study the design details of closely spaced battered pile,rib plate,lifting lug and superstructure connection and put forward corresponding solutions.The results show that the transmission coefficient of this type of breakwater can be reduced to below 0.2,and it is suitable for waves of higher heights and longer periods.
