摘　　要：针对在长周期波海域码头前期设计阶段如何通过数值模拟改进平面布置、减小影响的问题进行研究。采用WW3海浪模型、MIKE21SW模块以及MIKE21BW模块对长周期波进行较为全面的模拟,并根据实测资料进行验证。模拟步骤可作为长周期波波浪模拟的一般操作流程。为了更好地揭示长周期波对船舶的响应影响,将综合波分离为短波要素(<30 s)和长波要素(≥30 s),并将H_(s)<0.3 m作为初步判断标准。得出结论:码头布置需扩大掩护范围以阻挡长周期波主浪向,同时尽量缩减口门尺寸以降低长周期波输入能量进而降低港内波高。The problem of how to make the plane layout better and reduce the influence of long-period waves through numerical simulation in the early design stage of the wharf in long-period waves sea area is studied.This paper uses the WW3 ocean wave model,MIKE21SW module,and MIKE21BW module to conduct a more comprehensive simulation of long-period waves which is verified based on the measured data.The simulation steps can be used as a general operation procedures for long-period wave simulation.To better reveal the impact of long-period waves on the ship's response,the integrated waves are separated into short wave elements(<30 s)and longwave elements(≥30 s),and H_(s)<0.3 m is used as the preliminary judgment standard.It is concluded that the port general layout needs to expand the shielding range to block the main wave direction of long-period waves,and at the same time minimize the size of the entrance door to reduce the long-period wave input energy and reduce the wave height in the port.
