Structure Comparison,Selection and Cost Analysis of Gravity Wharf in Some Port

As for the gravity wharf structure of 100,000 DWT general-cargo terminal along batholithic coast,technical and economic comparison is carried out for caisson and block structure options,meanwhile,cost analysis is made for them.According the above comparison,selection and analysis,as water depth increases,wharf section is enlarged,and block structure option is obvious short of integral property.In that case,caisson structure should be adopted in the gravity wharf project.
