This paper puts forward the preliminary technical solution for the dredging and filling of the deepwater channel dredged soil in the 13th five-year period based on the analysis of the dredging and filling process,supply and demand relationship of dredged soil and natural conditions of the reclamation project.The conclusions are as follows.Dig-blowing and bow-blowing are only applicable to the short-distance dredging and filling project.The newly developed trailing suction hopper dredger (TSHD) loading barge technology,which is suitable for the long-distance dredging and filling project,can greatly expand the using space of the deepwater channel dredged soil.In the 13th five-year period,the seventh and eighth reclamation projects of Hengsha east shoal can use dig-blowing and TSHD loading barge technology to fill the deepwater channel dredged soil in the section of North Passage.N1 subarea of Nanhui east shoal reclamation project can use TSHD loading barge technology to blow the dredged soil of deepwater channel.Other scattered reclamation projects that belong to the construction land can use bow-blowing technology to fill the deepwater channel dredged soil in the section of the South Channel to Yuanyuan shoal.
