摘　　要：根据黄茅海实测资料对海岸工程水动力学数学模型进行了充分验证,并采用验证后的模型对台风、大潮同时作用的"二碰头"以及台风、大潮、洪水同时作用的"三碰头"两种极端水文条件下的黄茅海流场进行计算。结果表明两种极端情况发生时,各流速特征值在崖门口处明显增加,口外"二碰头"落潮时减小,涨潮时增加,"三碰头"各流速特征值也基本都呈增加趋势,增幅相比"二碰头"较大。The Model of Coastal and Ocean Engineering is validated by observed data of the Huangmao Sea. Then the model is used in current calculation for the Huangmao Sea in extreme hydrology conditions which are the meeting of typhoon and spring tide and that of typhoon, spring tide and flood. The solutions showed that, when the extreme conditions arise, all the velocity characteristics increase distinctly near Yamen. In other places, the characteristics of flow field decrease at ebb tide and increase at flood tide when typhoon and spring tide meet. When the meeting of typhoon, spring tide and flood happens, all the characteristics of flow field increase significantly, and the range of increase is greater than that of the meeting of typhoon and spring tide.
