象山湾港区规划方案泥沙淤积分析

采用平面二维潮流数学模型,对象山湾港区规划方案实施前后的流场进行了数值模拟,并在此基础上运用泥沙数学模型模拟该区域含沙量场的分布,进而对规划方案泥沙淤积情况进行分析。根据数值模拟和分析的结果对规划方案进行了评价并提出建议。研究结果表明,象山港所在海区泥沙运动以悬沙为主,规划方案实施后对该港区的泥沙运移不会产生大的影响;从潮流和泥沙角度分析,该港区规划方案各码头泊位布局合理。根据研究结果建议象山湾的港区码头宜顺岸布置并坚持深水深用、浅水浅用的原则。

Study on silt accumulation of planning project in Xiangshan Bay Port Area

This paper adopts the 2-D tidal flow mathematical model to realize the simulation calculation of the flow field features before and after the implementation of planning project in Xiangshan Bay.On the basis stated above the sediment concentration distribution is simulated by the sediment mathematical model.Moreover,silt accumulation of planning project is analyzed.According to the results of numerical simulation and analysis,some comments and suggestions are put forward.The results obtained indicates that the suspended sediment is the chief sediment motion in Xiangshan Bay,and the implementation of planning project won't impact the sediment motion.Arrangement of port berthage is reasonable from perspective of tidal current and sediment.It should along shore while following the principle of "Utilizing Deepwater for Deep Use,and Shallow Water for Shallow Use" according to the results in this paper.
