Abstract:With the joint operation of the two dams and thirteen gates of the Three Gorges Gezhouba cascade hub,the navigation conditions in the upper reaches of the Yangtze River have been greatly improved,the shipping costs of ships have been reduced,and the development of Yangtze River shipping has been promoted.The freight volume has been continuously increasing,reaching a capacity of 100 million tons ahead of schedule in 2011.However,with the rapid growth of freight volume,the problem of ship backlog caused by insufficient capacity of the Three Gorges Gezhouba cascade hub ship lock is becoming increasingly severe,and the problem of ship waiting for lock has become a normal situation.Strengthening the research and construction of anchorage engineering in cascade hubs is an urgent requirement to ensure the safety of ships waiting for gates,carry out safety inspections of ships waiting for gates,maintain the navigation order of ships,and improve the navigation efficiency.Therefore,this article proposes a construction plan for the Three Gorges Gezhouba cascade hub anchorage by sorting out the functional positioning and layout requirements of the anchorage,combined with the progress of scheduling technology and the innovation of methods such as the matching operation of the two dam ship locks.
