摘　　要：上海南汇嘴控制工程位于长江口和杭州湾交汇的南汇边滩，是上海市滩涂资源开发利用的重点工程．该海域受径流、强潮和波浪的相互影响，对控制工程的成败起着重要的作用．应用波浪作用下二维潮流数学模型和第3代近岸海浪模式SWAN，建立了二雏波浪潮流数学模型．根据2006年8月大潮实测水文资料和大戢山站1979～1998年和杨梅嘴站1997年8月～2001年7月实测波浪资料，对模型进行了全面的验证．结果表明，数值模拟海域潮位和定点垂线流速、流向、波高的计算值与实测值吻合良好．重点研究了圈围工程对附近的长江口南槽、杭州湾北岸、东海大桥、天然液化气管线南汇登陆点及洋山深水港区的水流及波浪的影响和变化．Located in the Nanhui Beach, where the Yangtze River estuary joins up Hangzhou Bay, Shanghai Nanhuizui inning project is the key project for developing and utilizing Shanghai tideland resources. The interactions between currents, tides and waves in the sea area perform an important function to the success of this project. A two-dimensional numerical model tidal current and the third-generation nearshore wave model SWAN were applied to establish the two-dimensional wave-current numerical model. The model was verified by the hydrology data measured in August 2006 and the wave survey conducted between 1979 and 1998 in Dajishan station and between August 1997 and July 2001 in Yangrneizui station. The results indicate that it has good agreement after comparing the modeled tidal levels, tidal current velocity, direction and significant wave heights with measurements. This study also emphasizes the effects and changes on the current and wave caused by the inning project around the south passage of the Yangtze Riv- er estuary, the north shore of Hangzhou Bay, the Honghai Bridge, the landing point closing to LNG pipeline, and the Yangshan deep water harbor.
