| It is of great significance to ensure the smooth,safe and efficient navigation hub of the large-scale ship locks on Xijiang River and the Yangtze River.Aiming at the problems that the three elements of lock-ship-channel have many influencing factors and strong coupling,channel water flow is unsteady,water level has high amplitude and fast rate of change,etc.,the multi-dimensional analysis modeling and simulation of large-scale ship lock passing capacity,unsteady flow down ship lock channel of hydrodynamic characteristics analysis,multi-constraint unsteady ship-lock hydrodynamics refinement modeling and other methods are studies.These methods overcome the problems of navigating the middle channel of the lock under complex and changeable conditions,rapid lock-passing under the cooperation of new standard ship types and locks,and key technologies for improving large-scale ship lock passing capacity such as capacity expansion construction engineering design,as well as key technologies for joint operation safety control such as large-scale ship lock linkage safety control,key equipment operation intelligent monitoring,and navigation safety risk prevention and control.The efficient and safe navigation engineering technology system for large-scale ship locks on Xijiang River and the Yangtze River is built.An integrated management and control platform for general aviation dispatching and safety is established.From the aspects of multi-scale dynamics,digital twins,intelligence and localization,and green ecological technology,the development direction of large-scale ship lock navigation operation technology is prospected. |
