摘　　要：非线性和移动边界问题是水动力数值模型研究的重要内容。本文详细地介绍了二维非线性动边界有限元法的水动力数值模型及其软件,并应用于杭州湾、湄州湾、泉州湾和三亚湾等水动力条件差异悬殊的水域。成果表明:该模型具有计算精度高、使用方便和适用范围广的特点,适合于河口、海岸等浅海水域;当研究对象为岸线曲折、岛屿礁石众多、拥有大面积潮间带、浅滩和深槽交错分布的复杂水域时,此模型的优点尤为突出。The nonlinear moving boundary problem is one of topics in numerical hydrodynamic modelings. A two-dimensional finite element modeling with moving boundaries and the related software are presented in this paper. In Hangzhou Bay, Meizhou Bay, Quanzhou Bay, and Sanya Bay etc., the above modeling is used successfully, and there are highly different hydrodynamic conditions in these regions. This modeling possesses good accuracies, flexibilities and wide fields of application. Its advantages are obvious for various regions with a certain complex topography.
