Abstract:The high-piled wharf can accommodate the feature of large water level differences in inland rivers by establishing multiple levels of mooring platforms,which usually adopts steel structures.To the problems of susceptibility to corrosion and high construction and maintenance costs of steel structures,this paper takes the mooring platform structure of the high-piled wharf as the research object and conducts a comparative study of steel structures and optimized concrete structures.By using finite element analysis software for three-dimensional modeling,the stress conditions of the beams and pile foundations are analyzed,and the investments of the two structures are compared.The results show that the optimized concrete structures can increase the integrity of the mooring structure at the front edge of the wharf platform,effectively reduce the maximum bending moment of the pile foundations,and the structure is more favorable.However,the bending moment and shear force of the beams have increased to a certain extent.The optimized concrete structure can significantly lower the project cost and reduce the subsequent maintenance efforts.
