Abstract An appropriate finite element model was given according to the actual process of jacked pile. This model adopted the rational constitutive model of soil and finite deformation theory. Through pile-soil contact and displacement loading on pile top, the pile-sinking process was simulated. Displacement fields were studied through the finite element model. The effects of displacement fields caused by pile-soil friction were discussed. Then comparisons between pile-soil interacting model and cavity expanding model were made. The results show that the pile-soil interaction and interface fiction are important influential factors in the simulation of jacked pile.
