In this paper,we carry out the three-dimensional finite element numerical simulation by using ABAQUS software for the piled wharf with monolithic box-slab superstructure scheme.By using ABAQUS’s unique skinning technology and user subroutine,we achieve the accurate simulation of the internal forces of the pile foundation and the dynamic loading of the portal crane load respectively,and optimize the structure according to the numerical simulation results.Comparing the results of calculation with ANSYS,and the two computed results agree reasonably well.The detailed structure simulation is more accurate and reasonable.It shows that the simulation method in this paper based on ABAQUS is more accurate and feasible.
