| 摘 要： | 本文用轴对称有限元法分析了桩基的蠕变效应。用广义开尔文模型和宾汉姆模型来分别模拟土的粘弹和粘塑性状。推导了轴对称条件下桩土接触面及桩周土体的粘弹、粘塑性应变增量公式。在此基础上编制了轴对称弹-粘弹-粘塑性有限元程序,分析了桩基的沉降、承台的荷载分担作用,以及桩体的侧阻力分布等受蠕变的影响,比较系统地研究了桩基的蠕变效应。此外,还进行了桩土接触面的摩擦试验研究。

| Abstract: | The axisymmetric finite element technique is used in this paper to analyze the creep effects on pole foundation. Generalized Kelvin model and Bingham model are proposed to simulate the viscoelastic and viscoelastic behavior of soil respectively. Viscoelastic and viscoelastic strain incremental formulas are derived for interface elements and soil elements around piles and the axisymmetric elastic-viscoelastc-viscoplastic finite element program is compiled. Creep effects on the settlement of poles, the building load carried by raft and the distribution of stresses along piles are analyzed. In addition, the behavior of interface between pile and soil are investigated through experiment. |
