摘要: 通过对超长桩载荷试验的研究,分析了超长桩的承载性状与普通钻孔桩之间的区别,并总结了超长桩的承载特性及荷载传递机理:①桩长是有限度的;②桩侧摩阻力和桩端阻力发挥是不同步的;③当达到设计荷载或允许沉降时,桩侧阻力还未发挥完全;④超长桩桩端阻力所占比例极小;⑤桩侧阻力呈现出完整的抛物线形态;⑥沉降曲线为缓变型,没有明显的拐点。
关键词: 超长桩, 承载性状, 传递机理
Abstract: The static loading tests are performed on the extralong cast in place concrete piles. The performance differences between the extralong piles and the conventional piles are evaluated. The characteristics and the loading transfer mechanism of the extralong piles are summarized in the paper.
Key words: Extra Long Piles, Bearing Capacity, Loading Transfer
