Abstract: Aiming at the problems occurring in actual projects, using the displacement penetration method, the complete process of successive penetration of jacked pile is simulated with finite element method based on ANSYS. Displacements and stress field in homogeneous soil are compared with which in layered soil in detail. It is shown that the soil’s displacement increases; and radial compression stress changes rapidly and discontinues at the boundary of soft soil and hard soil; and piles driven before are prone to be broken there.The methods for prevention is put forward.

Key words: layered soil, jacked pile, squeezing effects, stress discontinuity
