道路施工中软土地基施工加固技术实践

Practice of Reinforcement Technology of Soft Soil Foundation Construction in Road Construction

为强化地基稳定性、紧密性,减少道路断裂沉降问题,延长道路使用寿命,推进城市化建设进程,为交通发展奠定良好基础,分析了主要的软土地基加固技术,即加固土桩法、水泥粉煤灰碎石加固法、换填法、堆载-排水固接法。以某市政道路施工项目为例,分析软土地基加固技术实践,形成了高质量、高稳定性的路堤下隔层,解决了不均匀沉降问题,缩小了沉降差。

In order to strengthen the stability and tightness of the foundation,reduce the breakage and sedimentation of the road,prolong road service life,promote urban construction process,and lay good foundation for transportation development,the research analyzes the main soft foundation strengthening techniques,i.e.compacted soil pile,cement fly ash crushed stone reinforcement method,replacement method and stowage-drainage connection.Through taking municipal administration path construction project as an example,the research analyzes the practice of soft soil foundation strengthening technique,in order to form the embankment interlayer of high quality and high stability,solve the problem of differential settlement,and reduce the differential settlement.
