Abstract: Single pile cap model of PHC tubular pile is tested on the shaking table and 3 Dfinite element model is established considering the soil-PHC tubular pile-superstructure as integrity.The ABAQUS software is taken as calculation platform to numerically simulate the seismic responses under single pile test conditions.The simulation results and the shaking table rest records are compared in detail.It indicates that the simulation results are basically identical with those of shaking table tests,and both of them reflect similar seismic response regularity.The reliability of model tests and rationality of numerical simulation are proved.
