非饱和–饱和状态下黄土地基中灌注桩承载性能的研究

Research on bearing capacity of cast-in-place piles in unsaturated to saturated loess

    摘要
  • 摘要: 通过黄土地区大量的室内取样试验、现场桩基荷载浸水试验资料的分析与研究,揭示了黄土在含水率递增过程中抗剪强度的变化规律、非饱和–饱和状态下桩侧摩阻力的发展变化以及桩端在砂层、卵石及黄土条件下的附加沉降变形,建立了黄土地区桩侧摩阻力和单桩承载力的经验公式,供岩土工程技术人员在实际工程中参考使用。

     

    Abstract: Based on a great number of laboratory tests on soils and loading tests on cast-in-place piles in the loess region,the rules of the shear strength decreasing with the increasing of moisture content of the loess,the development and variation of skin resistance and the additional settlement deformation of piles with saturation of unsaturated loess were found.The emperical formulas of the skin resistance and bearing capacity of piles were set up for the loess.
