In Meizhou Bay Shimen’ao Land Reclamation Phase 1 Project(C bid),an alternative scheme was brought forward to fulfill the demand of forming reclamation area quickly with hydraulic filling conditions,which the original design couldn’t realize.By analyzing soil quality within sand borrowing area,the optimal scheme of cutter suctiou dredger(CSD)pumping sand directly to build reclamation weir was adopted,which fulfilled the project requirements,saved cost,shortened duration and maximized the overall efficiency of CSD.
