| 摘 要： | 基于秘鲁钱凯港的防波堤三维整体模型试验结果,研究了涌浪绕射、透射联合作用对港内波况的影响。分析了不同波向、不同谱峰周期的入射波条件下港内不同功能区的波况分布规律,并对比分析了具有不同周期的入射波对港内不同区域波高的影响,兼顾分析了波向的影响。结果表明,在涌浪作用下,受透射、绕射影响,不同入射波条件下港内比波高分布规律相关性较好,距离口门越近、入射波波长越长,港内比波高越大;入射波周期对港内波况影响的差异和对波向的敏感性因港内不同区域而不同;防波堤阻挡效果好的波向,其入射波对港内的影响较小;对于受防波堤掩护性较好的内侧泊位,应重点关注泊位处的低频波浪对系泊的影响。

| Abstract: | Compared with wind waves,surges with longer period can more easily cause adverse effects to the productive activities in the harbor,so that more and more attention has been paid to the impact of surges in today's harbor design,Based on the three-dimensional overall model test results of the breakwater in the Chancay Port of Peru,the influence of the combined action of surge diffraction and transmission on the state of waves within the harbor is studied.The distribution of wave states in different functional areas of the harbor under the condition of incident waves with different wave directions and different spectral peak periods is analyzed,and also the influence of the incident waves with different periods on the wave heights as well as the wave directions in different areas of the harbor is compared and analyzed.The results have showed that under the surge action the distributions of wave height ratio within the harbor under different incident wave conditions have better correlations due to the affection by transmission and diffraction.The closer the distance to the entrance and the longer the wavelength of the incident waves,the greater the wave height ratio within the harbor.The influence of the incident wave period on the wave state in the harbor and the sensitivity of the wave state to the incident wave direction vary in different areas within the harbor.In the areas where breakwater has a better function for blocking the wave direction,the influence of the incident waves on the inner parts of the harbor is small.For berths which are well protected at the inner side of the breakwater,the impact of the low frequency waves on the mooring should be focused on. |
