Abstract:
      The seabed scouring and silting are very important to the construction of port and waterway engineering. Seabed deposition and erosion change is complicated due to the influence of sediment supply, human activities and other factors. The Yangshan Deepwater Port is the new deep water harbor, which is an important part of the Shanghai International Shipping Service Center. Its construction has received much attention. At present, the water depth from the 1st to the 3rd harbor district is currently suitable under regular dredging and tidal current action. The fourth harbor district will be built in the world's largest fully-automated deep water wharf. In the study, bathymetry change of the entire sea area of the Yangshan Deepwater Port and the 4th harbor district (i.e., Phase IV project) waters were analyzed quantitatively using multiyear bathymetric, hydrological and sediment data. The results show that from 1998 to 2010, seabed changes are characterized by large volumes of erosion and sedimentation, which the southern part was deposited and the northern part was eroded in the inner harbor waters, but the seabed of the Kezhushan inlet was eroded. Seabed changes of Phase IV project waters generally show a scour tendency in recent few years with the annual scour rate about 0.7 m. Among the many factors, the existence of Kezhushan inlet and its influence of the western water flow play an important positive role in water depth changes under the ebb tide action.
中文摘要:
      海床冲淤变化对港口与航道工程建设非常重要。由于泥沙供给、人类活动和其他等因素的影响,海床冲淤变化非常复杂。洋山深水港是一个新兴的深水港口,是上海国际航运中心重要的组成部分,它的建设引起了各方的广泛关注。目前,洋山水深港一、二、三期港区在潮流运动和定期疏浚下保持着良好的水深。四期港区工程是世界上最大的全自动化深水码头,2017年12月以开港运行。本论文基于大量的地形资料、水文泥沙资料,分析了整个洋山深水港多年来的海床冲淤变化和近期四期工程海域海床冲淤变化。结果显示:1998-2010年整个洋山港区海床冲淤变化表现为较大幅度的冲淤,在洋山主通道内呈现为"南淤北冲"的格局,但是颗珠山汊道一直以来均表现冲刷的趋势;四期港区水域近一些年来也表现为一个冲刷的趋势,多年年均冲刷幅度0.7m左右;讨论了外界泥沙供给、港口工程陆域边界封堵、港池疏浚和由此带来的水流的变化以及泥沙水力特性等因素的对洋山港海域海床冲淤变化的影响,在众多因素中,颗珠山汊道的存在(或保留)对洋山西部水域或四期港区水域冲刷有着积极的作用,它的存在所产生的落潮作用对四期港区的水深维护起到重要的正面影响。
