  • Based on the hypothesis that the pile driving process is regarded as cavity expansion,according to two-parameter parabolic failure envelope and the cavity expansion theory,the driving effect of the tubular pile is studied.The elasto-plastic analysis solution of the stress field and displacement field of the soil around the pile are given.The radius of plastic zone and the limit expansion pressure are obtained.It can provide theoretical supports for some tubular pile engineering practices.
