连云港港赣榆港区起步工程泥沙问题研究

Research on Sediment Problems in Initial Project in Ganyu Port Area of Lianyungang Port

泥沙问题是连云港港北翼的赣榆港区和航道建设的关键问题之一。文中在进行自然条件分析的基础上,利用MOHID二、三维潮流泥沙数学模型对该港区实施后的潮流场及港池、航道泥沙回淤进行了计算模拟,对不同工况潮流流态、航道横流及对周围海区影响范围进行了分析,不仅给出不同工况下港池和航道的年回淤值,还对9711号台风作用下港池和航道的骤淤情况进行了计算预报。综合以上研究成果,提出推荐方案。

Sediment is a key problem in the construction of navigation channel and Ganyu port area,which is the north flank of Lianyungang port.On the basis of the analysis of natural conditions,suspended sediment concentration and distribution characteristics of bed material,tidal current field and siltation of harbor basin and channel are simulated by using a 2D and 3D MOHID tidal flow and sediment mathematical model.The tidal current field,yearly sedimentation in the harbor basin and channel is not only presented in the paper,but also sudden sedimentation in harbor basin and channel under the effect of No.9711 tropic storm is computed.Finally,by synthesis of all the above achievements,an optimum scheme is put forward.
