摘　　要：根据夯实水泥土桩试验所得到桩身应力-应变关系和桩侧摩阻力与桩土相对位移的关系,运用荷载传递法结合Geddes公式对夯实水泥土桩的承载机理进行分析,探讨其临界桩长,分析桩身材料无侧限强度qu、桩侧摩阻力τu、桩的直径d对临界桩长的影响,并在此基础上提出夯实水泥土桩的临界桩长建议值。Based on the stress-strain relationship, the non-linear relationship between the shaft resistance and pile relative displacement of rammed soil-cement pile loading tests, through numerical analysis method, beating mechanism and critical length of rammed soil-cement pile are studied. Influence factors of critical length, such as rammed soil-cement limit strength qu, shaft resistance ru and diameter d, are thoroughly analysed. Proposed critical length of rammed soil-cement pile is given.
