Nanjing Port Master Plan(2024-2035)has defined the positioning and development direction of Nanjing Port.The trend towards larger-scale, more intensive port operations and the increasing size of ships entering and leaving the port has become inevitable, placing higher demands on the capacity of the Yangtze River waterway.On the basis of the port layout planning and the forecast of the maximum ship dimensions for different cargo types arriving at the port, as well as the navigable ship type dimensions on the main trunk of the Yangtze River, which is specified by national and industrial standards.We demonstrate typical ship types and target values for navigable channel dimension requirements of the Nanjing Port section upstream of Nanjing Yangtze River Bridge during the planning period, and conduct research on the adaptability of the waterway's capacity.The results show that the current navigable channel dimensions and the construction standards of waterway regulation projects cannot fully meet the requirements of Nanjing Port Master Plan(2024-2035), leading to the proposal of optimization strategies for navigable channel dimensions.
