摘 要:海上倾倒作为处理港口、航道建设产生疏浚物的主要处理方式,对海洋经济的发展起至关重要的作用。为深入研究倾倒区淤积物对周边地形变化的影响,本研究建立了二维水动力模型与泥沙模型。通过对疏浚物倾倒过程模拟计算结果进行详尽的分析,计算各倾倒区在疏浚物年倾倒后倾倒区内水深的变化情况,并将其与同工况下多倾倒区共同倾倒情况进行了对比。研究结果表明,共同倾倒后相邻倾倒区淤积厚度增加,限制倾倒区的原有容量。这一研究为后续多倾倒区容量评估提供了科学依据,可以为海洋倾倒区的合理规划与使用提供指导。Dumping at sea,as the main way to deal with the dredge produced by the construction of ports and waterways,plays a vital role in the development of marine economy.In order to further study the topographic changes and effects of the adjacent dump area on the surrounding dump area,a two-dimensional hydrodynamic model and a sediment model were established in this study.Through the detailed analysis of the simulation results of the dumping process of dredging materials,we calculated the change of water depth in the dumping area after the dumping of dredging materials in each dumping area,and compared it with the common dumping situation of multiple dumping areas under the same working condition.After joint dumping,the siltation thickness of the adjacent dumping area increases and the original capacity of the dumping area is limited.This study provides a scientific basis for the subsequent capacity assessment of multiple dumping areas,and is helpful to provide guidance for the rational planning and use of marine dumping areas.
