船舶交通流对受限水域护岸的动力作用机理研究

With the rapid developments of inland water transport, large scale, high speed and density vessel traffic become the main trends. The interaction between vessel traffic flow and waterway banks has been significantly enhanced, resulting in the challenges in traffic safety administration and infrastructure protection. The present study focuses on this dynamic mechanism in the confined area. Characteristic parameters are derived by multi-source heterogeneous vessel trajectory data. Ship wave characteristics are investigated by in-situ observations and laboratory model tests. System dynamic model is established between vessel traffic flow parameters and ship wave characteristics. Meanwhile, the incident ship wave is incorporated to the ANUGA model and the resulting wave hydrodynamics on the sloping bed is studied. The influence of boundary conditions will be quantitatively evaluated. Field measurements will be conducted at the upper reach of Yangtze River and Jianghan Canal for the validation of the numerical models..The present study aims to reveal dynamic mechanism between vessel traffic flow and waterway banks in the confined waters. The research is helpful to ensure ship navigation safety and development of ecological water transport.
