| 摘 要： | 采用SWAN模型建立曹妃甸海域波浪数学模型,计算了港口工程前后4个代表性波向（S,ENE,SW,E）的波浪场,分析了曹妃甸工程对该海域4个不同方向波浪传播的影响.计算结果表明：工程竣工后,港池、潮汐通道内的波浪场发生显著变化,波高、周期明显减小,波向的变化受控于入射波向和工程走向,而对于工程区以外海域的波浪特征影响甚微.

| Abstract: | Caofeidian is located in the seas to south of the city,Tangshan,Hebei province,which is a perfect natural place for deep-water harbor engineering.The study on the wave propagation in coastal area plays an essential role in the utilization of ocean resources and the implement of the harbor project.The numerical wave model was set up by applying SWAN model,and the wave fields under four representative wave directions（S,ENE,SW,E） in the coastal area were computed before and after the project of Caofeidian Harbor.The influence of the harbor project on the wave field was analyzed,and the computed results show that： the significant change in wave field caused by the harbor project is in the area of harbor basin and tidal inlet,where the wave height and period reduce significantly and the variation of wave direction is related to the incident angle and the engineering arrangements.There is no obvious influence on the wave field out of the engineering area. |
