摘　　要：在淤泥质海岸建港,泥沙回淤是必须考虑的首要问题。文中应用波流共同作用下的大范围泥沙数学模型,模拟计算了连云港港徐圩港区建设期不同布置方案下的泥沙回淤情况。研究结果表明:徐圩港区在建设期的回淤中,内航道所占比重较大,主要与港区水域面积有关。因此,在环抱式港区的建设过程中,应尽可能早地实施港区内的规划围垦项目,以达到防淤减淤的目的。Constructing a port in muddy coast, the sediment deposition must be considered primarily. This paper applied a sediment mathematical model with combined wave-current interaction to model the Sediment siltation in Xuwei Harbor, Lianyungang, China, during the construction period for different layout plans. The results showed that： the deposition in the inner waterway accounted for a large proportion, mainly due to the large water area in the harbor. Therefore, in order to pre- vent and reduce the deposition, the planned reclamation project in the encircle harbor area should be carried out as early as possible in the construction process.
