Combining with practical engineering,the paper introduced the application characteristics of the front sheet-pile and offside-low pile platform,and analyzed the technical points and considerations in the actual design.The front sheet-pile and offside-low pile platform structure is complex,and the original specifications are not completely applicable.Combining with practical engineering,and considering the factors such as the unloading of low pile platform and that the deflection of steel sheet pile cannot be completely restored,it conducted the three-dimensional numerical simulation to get the internal force of the main components in the wharf structure,and analyzed the influence of these factors on the structure from the aspects such as the connection mode between pile foundation and bearing platform,which provides the basis for structural design and optimization.
