垫层作用下石灰桩复合地基工作性状

The behavior of lime column composite foundation with the action of cushion

  • 摘要: 通过改变垫层厚度对石灰桩单桩复合地基进行模型试验。根据试验资料分析了桩、土荷载传递特性,桩、土应力变化规律及桩土应力比随深度的变化等工作性状,并就其在工程设计及实践中的应用进行了分析。

     

    Abstract: In this paper,model tests of single lime column composite foundation are carried out with cushions of various thickness.On the basis of test data we analyse the load transfer mechanism of lime column composite foundation, the law of the variation of column soil stress and stress ratio with depth and its application in civil engineering.
