摘　　要：波浪仿真是海岸工程领域中一件非常有意义的工作。但是,从目前海岸工程界两大类波浪数学模型研究来看,即:能量平衡模型和质量、动量守恒模型,都存在着巨大的计算量问题。若仅用一台微机进行计算,不能够得到实时动态的仿真结果。从网格计算思想出发,采用SWAN(SimulatingWAvesNearshore)模型,提出了网格计算的体系结构和基于网格计算的动态波浪仿真的建模,最后对近海岸波浪进行动态仿真。Simulating dynamic waves is a very interesting job in the coastal engineering practice. There are two types of wave mathematical models, namely, energy balance models and mass and momentum conservation models. To implement two models causes tremendous computing data. However, simulating a large scale of dynamic waves＇ evolvement is so difficult that it cannot be implemented by a microcomputer. A kind of grid computing architecture of wave simulation was presented based on grid computing philosophy and a grid modeling method of dynamic waves＇ simulation. At last, Simulation Waves Nearshore （SWAN） model to simulate dynamic waves was adopted.
