To solve the problem of shared deep-water shoreline between the wharf and the water intake,taking the reconstruction of Ligang power plant bulk cargo terminal in Shili Port District of Wuxi (Jiangyin) Port as an example,combined with the navigation and hydrological conditions of the project area and the characteristics of the reconstruction project,this paper analyzes different proposals of power plant bulk cargo terminal.Adopting the method of numerical calculation and theoretical research in different working conditions,the influence of hydrodynamic conditions in front of wharf under the scheme of wharf structure spans over the water intake is analyzed.The results show that when the wharf built with a transparent structure and spans over the water intake,the water intake has little influence on the hydrodynamic conditions of the wharf apron,and basically does not affect the normal berthing and operation of ships.It will achieve intensive and efficient utilization of shoreline,which provides a reference for the planning and design of similar projects.
