碎石桩结合反压护道法在公路软基处理中的应用

The Application of Gravel Pile Combined with Back Pressure Protection Method in Soft Foundation Treatment of Highway

尼日利亚某公路项目软基分布广泛,结合施工所在区域地质概况,提出"碎石桩+反压护道法"施工方案进行软基加固,对该方案施工技术要点进行具体分析,并结合工后沉降观测数据,最终得出结论:应用该工艺软基处理效果良好,值得借鉴。

Expressway soft foundation project in Nigeria are widely distributed,in combination with construction area geology situation,this paper puts forward the construction scheme of"gravel pile+back pressure road protection method"for soft foundation reinforcement.The key points of the construction technology of the scheme are analyzed in detail.Combined with the post-construction settlement observation data,the final conclusion is drawn:the soft foundation treatment effect of the application of this technology is good,which is worthy of reference.
