【摘要】 分析了路堤荷载下刚性桩复合地基中负摩阻力问题,对土体沉降采用 Terzaghi 一维固结理论,在假设桩及桩周土体变形规律的基础上得到了桩体轴力和变形的计算公式,与一个工程实例的测试结果具有良好的一致性;并讨论了负摩阻力随各种因素变化的影响规律。更多还原

【Abstract】 For the negative force along rigid pile under embankment loads,an elastic differential equation is established.The ground settlement with depth and time is derived from Terzaghi’s consolidation theory;and its distribution is supposed as one mode.The analytic solution for the pile in the homogeneous ground under embankment loads is derived.An engineering example is studied by this method;and all influential factors are discussed respectively.更多还原
