摘要:
根据桩土的位移协调条件、改进李海芳位移模式和有效桩长的定义,分析桩侧摩阻力在桩顶处最大时的柔性桩单桩荷载传递规律,得到柔性桩的桩身应力、桩侧摩阻力和有效桩长的计算表达式.实例计算结果表明:桩身应力和桩侧摩阻力均是在桩顶处最大,沿桩长的分布形式与试验结果较一致; 有效桩长与试验值非常接近,且比段继伟的建议取值稍大.
Abstract:
Based on the pile-soil displacement coordination,and the definition of effective length of single deformable pile,by improving the Alamgir displacement mode which was brought forward by LI Hai-fang,the load transfer law of deformable piles was analyzed when the maximum skin friction on piles is on the top of the pile.New formulas for axial stress,skin friction and effective pile length were proposed.The calculation result shows that the distribution of the axial stress and skin friction on pile is in accordance with the test result.The maximum values of axial stress and skin friction are located on the top of the pile.The theoretical value of effective length of pile agrees well with the test result,and is a bit greater than the value advised by DUAN Ji-wei.
