Selecting a project in Hong Kong,China as the engineering background,based on the characteristics of the construction site,a new cantilever steel structure berthing facility is designed to better adapt to the temporary construction needs of this project,and realize material recycling and cost saving.The difference and advantage between the new steel structure berths and the traditional wharf berths are compared and analyzed.Based on the local hydrological conditions,the internal force calculation and stability analysis are carried out using the finite element model.The results show that the shear resistance,bending resistance,tensile strength,compression resistance,buckling stability,and deformation of this new type of steel structural berth can all meet safety requirements,and it has the advantages of short installation period,low investment,and environmentally friendly recycling of the new berth.The research results can provide reference for the design and implementation of similar engineering projects.
