摘要
基于三维组合式抛石防波堤物理模型,开展了多向不规则波作用的港池试验,分析6组波浪条件所对应的掩蔽区域测点比波高分布图,得到主要结论:6组波浪条件所对应的测点比波高整体呈现从口门到掩蔽区域逐渐减小趋势,最大比波高位置在口门附近;当波周期TP=7 s、12 s、16 s时,不同水深h所对应的掩蔽区域测点比波高分布图的变化趋势基本一致,最大比波高位置分别在口门偏北方向、口门中心处、口门偏南方向,整体呈现随TP增大而向口门南方偏移趋势;当h=14.8 m、17.1 m时,掩蔽区域内同一测点比波高呈现随TP增大而增大趋势。
Based on the physical model of three-dimensional composite rubble mound breakwater,the harbor basin experiments of multi-directional irregular waves were carried out.By analyzing the distribution maps of wave height ratio of the measured points in the sheltered area under six groups of wave conditions,the following conclusions are obtained:the wave height ratio of the six groups of wave conditions decreases gradually from the entrance to the sheltered area,and the maximum wave height ratio is near the entrance;when the wave period TP=7 s,12 s,and 16 s,the change trends of distribution maps of the wave height ratio in sheltered area corresponding to different water depths h are basically the same,and the location of maximum wave height ratio appears in the north of the entrance,the center of the entrance,and the south of the entrance respectively,and the overall trend is shifted to the south of the entrance with the increase of TP;when water depth h=14.8 m and 17.1 m,the wave height ratio of the same measured point in the sheltered area increases with the increase of TP.
