Abstract:Since the reform and opening up, the coastal economy has developed rapidly, and hydraulic reclamation land has appeared in many areas, which requires that the site needs preliminary treatment before it can be delivered to other subsequent projects for construction. Taking the preliminary treatment of a hydraulic reclamation area construction site as an example, this paper compares and selects four suitable different schemes on the basis of meeting the project requirements, and then recommends the optimal scheme through the comprehensive analysis of cost and effect, which provides a useful reference for the scheme comparison and selection of Hydraulic Reclamation preliminary treatment projects.
