【摘要】 非直线型浮式防波堤相较于直线型布置，其对多浪向的掩护效果更佳，但波浪载荷特性也更加复杂。本文提出一种弧型布局的浮式防波堤布置方案，基于三维势流理论对其进行波浪载荷特性分析，计算不同浪向下的一阶波浪力和二阶波浪力，给出了典型剖面载荷。并与直线型布局浮式防波堤进行对比分析。结果表明采用弧型布局能够有效降低浮式防波堤结构一阶波浪力与二阶波浪力，并且使得结构在斜浪下的剖面载荷与横浪工况下趋于一致。更多还原

【Abstract】 Compared with the linear arrangement, the non-linear floating breakwater has a better shielding effect on multiple wave directions, but the wave load characteristics are also more complicated. This paper proposes an arc-shaped floating breakwater layout plan. Based on the three-dimensional potential flow theory, the wave load characteristics of the arc-shaped floating breakwater are analyzed, the first-order wave force and the second-order wave force of different wave downwards are calculated, and the typical section loads are given. Compared with the linear layout of the floating breakwater, the results show that the use of the arc layout can effectively reduce the first-order wave force and the second-order wave force on the floating breakwater structure, and make the section loads of the structure consistent under different waves.更多还原
