摘要
对竖向荷载作用下的不同桩体材料超长单桩进行模型试验研究,分析其承载机理和变形特性,研究两种材料超长单桩的荷载-位移特性,桩侧摩阻力、桩端阻力的发挥性状,桩侧摩阻力和桩-土相对位移的关系以及桩身压缩量。结果表明,桩身材料的性质在很大程度上影响了超长单桩的承载和变形机理,超长单桩设计中应重视桩身材料的选择。
Through design and implement of model test, the mechanisms of beating and deformation of simple super-long pile of dif- ferent materials under vertical load are analyzed and the characteristics of P-S curve,the side friction of pile,the tip resistance of pile, the relationship of pile parietal resistance and relative displacement between pile and soil and compression of pile are studied. The re- suits of analyses indicate that the influence of pile shaft material affects the mechanism of bearing and deformation of single super-long pile, therefore, the selection of material is necessary.
