摘要
文章针对常规的水泥土搅拌桩、GFG桩等复合地基在处理公路软土地基问题中存在的不足,分析了带帽PTC管桩应用于高速公路路基施工的优势,并结合某一级公路施工建设项目,介绍了带帽PTC桩的设计方案与施工工艺,以期对类似工程起到借鉴作用。
Regarding the shortcomings of conventional cement-soil mixing pile, GFG pile and other composite foundation in the treatment of highway soft-soil foundation,this article analyzed the advan- tages of using the PTC pipe pile with cap in expressway subgrade construction,and combined with a Grade I highway construction project,it introduced the design scheme and construction technology of PTC piles with cap,hoping to play the reference role for similar projects.
