| 摘 要： | 利用ABAQUS分析了当断桩出现在不同位置时,考虑钢筋笼作用对桩顶荷载沉降曲线的影响;同时利用软件自带的混凝土塑性损伤模型考虑了混凝土的非线性性能;然后通过对不同工况下拐点荷载增量、陡降位移以及桩侧摩阻力的分布规律的分析对以上现象做出了解释。

| Abstract: | The paper makes use of ABAQUS to analyse the influence of loading settlement graphs of free pile due to broken pile defect appearing in different locations when consider the impact of bare steel cage.Nonlinear properties of concrete also are considered by concrete plasticity damage model;furthermore,the paper explains why the phenomenon takes place by means of studying the regularity of distribution of pile side friction and the contrast of inflection point increments and plunged settlements in different working conditions. |

| Keywords: | breaking pile reinforcement cage loading settlement graph pile side friction |
