大直径灌注桩承载性状的试验研究

【摘要】 本文通过现场试桩资料， 分析了桩的荷载传递机理与承载性状， 对于大直径桩， 其变形特征为缓变型，不具有明显的破坏特征点， 其极限承载力或容许承载力的确定以位移控制，沉渣厚度对桩端阻力及桩侧摩阻力的发挥有重要影响。更多还原

【Abstract】 The loading transmission mechanism and bearing behaviours of pile are analyzed herein through field test data.There is no obvious failure features in large diameter pile and its ultimate bearing capacity or allowable bearing capacity is determined by displacement.The thickness of sediment is the major influence on tip resistance and side friction of pile.更多还原
