The complete process of successive penetration of single jacked pile is simulated with finite element method based on the commonly used large-scale software ANSYS; and compacting displacements are analyzed in detail. The displacement fields caused by different modulus ratios of pile to soil

frictions between pile and soil and Poisson’s ratios of soil are given. Some complex problems

such as elastoplastic constitutive law

stress field of soil ’s dead weight

large deformation and sliding friction between pile and soil

are taken into account by using the displacement penetration method which is more reality and has the effect of animated simulation.
