水泥搅拌桩在铁路桥涵地基处理中的应用

Application of Cement Mixing Pile in Foundation Treatment of Railway Bridge and Culvert

以某铁路小桥涵软土地基处理为实例,进行设计计算和推导桩间土承载力折减系数,通过载荷试验对比修正设计参数,使得处理后地基满足承载力需求,为同类设计提供一定参考。

Taking the soft soil foundation treatment of a small railway bridge and culvert as an example,the design calculation and deduction of the reduction coefficient of the bearing capacity of soil between piles are carried out and the design parameters are corrected through the load test comparison,so that the treated foundation can meet the bearing capacity requirements,providing certain reference for the similar design.
