The pile cap joint of the high-pile wharf is an important component to transfer the upper load of the wharf.For the single pile cap joint and fork pile cap joint of the high-pile wharf,the structural deformation,stress distribution,load displacement curve,and corner bending curve are compared by finite element analysis method under different embedment depth of the pile end.The numerical results show that when the cap joint of a single pile is subjected to horizontal load,the rotational stiffness of the structure in the early stage of loading is mainly provided by anchorage steel bar of the pile core,and in the later stage,it is mainly provided by the pile core concrete and steel pipe.When the embedded depth of the pile end is less than 0.50 times the pile diameter,the joint is a semi-rigid connection.When the cross pile cap joint is subjected to horizontal load,the yield of the anchorage steel bars at the tensile side of the pile is the main reason for the decrease in structural bearing capacity.It is recommended to be strengthen in the design.When the fork pile cap joint is subjected to the standard mooring force of 30,000 t general cargo ship,the influence of pile end embedment depth on the stress and displacement of the joint is less than 14%,providing scientific reference for the design of pile cap joint of high-pile wharf.
