摘要
在黄土地区抗拔桩现场试验的基础上,通过数值模拟,分析了等截面抗拔单桩在竖向上拔荷载作用下的变形特性,并探讨了桩长和桩身混凝土强度对抗拔单桩Q-s曲线、桩身轴力及桩侧摩阻力的影响,力图为黄土地区抗拔桩的设计及施工提供一定的参考.
Based on field tests of uplift piles in loess area,the bearing characteristics of single section uplift piles were analyzed under vertical uplift loads by numerical simulation.The influence of pile length and pile concrete strength were discussed on Q-S curve,axial force and side friction of single uplift pile.Some references are provided for design and construction of uplift piles in loess area through this paper.
