Key technology research and outlook for large ship lock navigation in Xijiang River and the Yangtze River
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.
