摘　　要：采用有限元分步杂交方法,在已建潮流场的基础上,建立了胶州湾疏浚物悬浮泥沙的二维输运-扩散模型,并应用于胶州湾前湾港区泛亚码头工程疏浚区的疏浚物输运扩散的数值模拟预测。根据预测结果分析了泛亚码头疏浚区施工期间悬浮泥沙对附近海域水环境和生态环境的影响,并对不同的疏浚方案进行了优选。Using the split steps finite-element method, a two dimensional model of the transport and diffusion of suspended particulate matter of dredged matter in Jiaozhou Bay was established based on a simulated tidal current field. This model was applied to numerical simulation predicition for transport and diffusion of dredged matter near Fanya Dock Qianwan Port Area in Jiaozhou Bay. According to the predicition results the effects of the suspeded particulate matter on the water environment and eco-environment in the wharf area of Jiaozhou Bay were analyzed. And the optimum scheme was selected from different schemes of dredging.
