STUDY ON BEARING MECHANISM AND CRITICAL LENGTH OF RAMMED SOIL-CEMENT PILE
-
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u、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。Abstract: 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,bearing mechanism and critical length of rammed soil-cement pile are studied.Influence factors of critical length,such as rammed soil-cement limit strength q-u,shaft resistance -u and diameter d,are thoroughly analyzed.Proposed critical length of rammed soil-cement pile is given.
