摘要: 基于Poulos桩顶受荷的弹性理论解,对O-cell试桩法在桩端受荷条件下桩侧摩阻力和桩身位移的弹性理论公式进行推导。通过编制相应的计算程序,给出O-cell法试桩条件下桩侧摩阻力和位移沿桩身的分布,并对桩的长径比和桩土刚度比对侧阻与位移沿桩身分布的影响进行分析。Abstract: Based on Poulos's elastic theory method of pile under loading from the top,an analytical solution for pile when loaded from the bottom is deduced during the O-cell testing pile.According to the results of the computational program,the distribution of the shaft friction and displacement along the pile are given and the factors affecting the distribution such as the ratio of pile's length-to-diameter and the stiffness ratio of pile-to-soil are analyzed.
