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.
