摘要
根据龙口、蓬莱海洋站实测波浪资料,分析烟台港栾家口港区和蓬莱东港区的波浪特性,结果显示该海区属于以风浪为主、涌浪为辅的混合浪。利用TK-2D的PEM波浪数学模型模拟工程前波浪,得到工程区设计波要素,栾家口港区的强浪向是偏WNW向,蓬莱东港区的强浪向是偏NE向。利用MIKE21的BW方程波浪数学模型对平面布置方案下港内的波况进行模拟。在掩护水域由于采用直立式码头,波浪发生多次反射,码头前波高较大,为减小港内波高,对方案进行优化,采用高桩等反射率小的码头结构型式,可以消散港内波能,有效减小码头前波高。
Through measured data of Penglai and Longkou station,the wave characteristic was studied.The results show that the wave is mixed by wind wave and swell,and dominated by wind wave.The design wave condition of the project was obtained by TK-2D wave numerical model.The direction of strong wave in Luanjiakou Port is WNW, and in Penglai Port is NE.The wave conditions of different options were simulated based on BW wave mathematical model of MIKE21.Because of adopting the vertical type wharf in sheltered waters,multiple reflection of wave occurs, and the wave height in front of the wharf is comparatively large.The type of wharf is changed from vertical to high pile in order to dissipate wave energy and reduce the wave height in sheltered waters.
