New Type of Semi-Circular Estuary Jetty Structural Design for Yangtze Estuary Deepwater Channel Regulation Project

This paper describes the application of semi-circular breakwater at home and abroad and the design innovation and optimization of semi-circular jetty in Yangtze Estuary Deepwater Channel Regulation Project,esp.the design of estuary jetty structure using semi-circular floating caissons;A new calculation method for wave forces acting on the submerged semi-circular estuary jetty and the optimization design method for semi-circular structures are recommended.
