宝钢马迹山矿石码头工程潮流问题研究

Study on the tidal current of Baosteel Majishan ore wharf project

上海宝钢马迹山中转港扩建卸船码头东端涨潮水流湍急,水流流向与码头走向之间有20°左右的夹角,影响船舶靠离泊安全。模型试验表明,整治工程“东导流堤”可以有效地改善扩建卸船码头东端水流条件。西侧的装船码头水域范围内,由于马屁股岬角的挑流作用,落潮期在装船码头水域形成大尺度回流区;模型试验表明,采用整治工程“西导流堤”的“中”或“北”方案,均可解决装船码头水域回流问题;不宜采用布置在马屁股岬角处的“南方案”。

In the east end of the unloading wharf of Shanghai Baosteel Majishan transfer port expansion project,the tide current was rapid,and there was an angle of about 20°between the flow direction and the wharf trend,which affects the safety of ship berthing.The model test shows that the regulation project"East diversion dike"can effectively improve the flow conditions at the east end of the expanded unloading wharf.However,in the water area of the loading dock on the west side,a large-scale backflow area was formed during the ebb tide period due to the role of the flip-flop of the headland;the model test shows that the"middle"or"North"scheme of the regulation project"West diversion dike"can solve the backflow problem;the"South case"arranged at the headland is not suitable.
