Study on optimization requirements of ship crossing dispatching rules in Three Gorges and Gezhouba reach

On the basis of in-depth analysis of the historical evolution and current implementation conditions of the three Gorges-Gezhouba reach, this paper carries out the optimization requirements analysis of the scheduling rules. Through the consideration of the current navigation dispatching practice, the optimization idea of the dispatching rules is put forward, aiming to provide more scientific and reasonable guidance for the navigation dispatching of the Three Gorges-Gezhouba reach, so as to better meet the needs of ships, promote the development of the Yangtze River Economic Belt, and provide strong support for the regional economic prosperity.
