| Abstract: | In the first dredging and pumping ashore project in the Yangtze River,unprecedented difficulties and technical problems were encountered during the construction.Based on the analysis of the Yangtze River,fine silt,clay and other complex project conditions,the drag head and teeth were improved,the craft parameters of dredging and the program of pumping ashore were optimized,which improved the construction efficiency and provided reference for the future dredging and pumping ashore construction of self-propelled trailing suction hopper dredger in the Yangtze River. |
