摘要
人工填土由于其特殊的工程地质性质 ,难以作为基础持力层 ,将主要用于软土地基处理及消除黄土湿陷性的CFS桩推广到填土中 ,通过现场测试 ,证明其有效性 ,并对CFS桩复合地基承载力特性、桩土应力比、荷载分担比及桩间土的改良效果进行了分析论述。
It is difficult to use man made fill for foundation bearing stratum.CFS pile was adopted mainly for soft soil subgrade and for elimination of collapsibility of loess,but now its use can be extended to man made fill.Through field tests its effectiveness was tested.Bearing capacity of CSF pile composite subgrad,pile soil stress ratio,loading distribution and the improvement of soil between piles are analysed.
