宁波舟山港条帚门航道扩建方案研究

Expansion plan of Tiaozhoumen Channel in Ningbo Zhoushan Port

为进一步缓解虾峙门航道通航压力,避免类似“苏伊士运河堵塞事件”等极端情况的发生,保障宁波舟山港核心港区“双循环”,迫切需要提升条帚门航道的通航能力。针对岛礁海域特殊的自然条件和多船型混合航行要求,通过潮流泥沙数学模型、船舶模拟试验、交通流分析等研究手段,提出了条帚门航道平面布置和设计尺度方案。采用长航道多站联合乘潮方法合理确定各区段乘潮水位,有效降低疏浚标高、建设费用及维护难度。该项目设计理念、研究方法及成果可供类似工程参考。

In order to further alleviate the navigation pressure of the Xiazhimen Channel,avoid extreme situations such as the Suez Canal blockage incident,and ensure the"dual circulation"of the core port area of Zhoushan Port in Ningbo,it is urgent to improve the navigation capacity of the Tiaozhoumen Channel.In response to the special natural conditions and mixed navigation requirements of multiple ship types in the island and reef waters,a plan layout and design scale scheme for the Tiaozhoumen Channel were proposed through research methods such as tidal sediment mathematical models,ship model simulation experiments,and traffic flow analysis.The use of a long channel and multi station combined tidal method to reasonably determine the tidal water level in each section effectively reduces dredging elevation,construction costs,and maintenance difficulties.The design concept,research methods,and achievements of this project can be used as a reference for similar engineering projects.
