摘要
以某高速公路桥梁试桩试验为依托,对软土地基桥梁钻孔灌注桩的桩侧土层摩阻力实测值大于规范值、极限端承力大于实测土体极限端承力的原因进行了讨论,实践表明,合理地估计桩侧摩阻力,不仅有利于基础的优化设计,还将带来极大的经济效益。
On the basis of bridge trial pile experiment of one freeway,it discusses the measured value of friction drag bigger than the gauge value and the limit bearing of the end bigger than the measured soil limit bearing of the end.Practice illustrate,it is not only good to the optimum design of the foundation,but also brings the big economic benefits of reasonable estimate the friction drag of the pile sides.
