摘要
文章针对软土地基公路扩建的特殊工程特性,提出了粉喷桩加固处理地基的方法,阐述了粉喷桩复合地基的参数选择、计算方法及模型建立,并对比分析了不同加固深度、不同置换率的粉喷桩对扩建高速公路软土地基变形的影响。
Aimed at special construction requirement for expanding soft foundation road,the article proposes the method of using power spraying pile to strengthen the foundation.It dis- cusses its index selection,calculation method and model building.It also pedorrns compari- son analysis on the influence of power spraying pile with difference strengthening depth and exchange ratio on the deformation of expanding highway soft foundation.
