Using numerical simulation method,we analyze the influence of the pile-beam joints’connection type to the horizontal force state by changing the pile-beam joints’stiffness of high-piled wharf for different connection types.It is pointed out that the pile-beam joints’connection type of high-piled wharf has a significant effect on its stress and displacement,and the general law on joints’connection type to the force state about the all-vertical-piled wharf and fork pile wharf is obtained,which may serve as reference for evaluating the wharf’s bearing performance.
