摘要
CFG桩形成的复合地基结构体系其承载力大且可调性强、沉降变形小、稳定快、无有效桩长的限制,在路堤填筑施工期间,在工后其累计沉降量均小于其它传统的软基处理方法。可以大量应用于道路深厚软基的处理,在加宽段、滑塌段、结构物软基处理、桥台差异沉降、高路堤快速填筑等软基处理段具有较高的技术经济效益,其推广应用价值较高。
CFG pile composite structural system formed its foundation bearing capacity and adjustable and strong,settlement deformation is small,fast and stable,no effective length of the restrictions during the Embankment Construction,cumulative settlement after workers were less than other traditional soft ground treatment.Can be applied to deal with a large number of deep soft foundation of road,in widened section,slumping segment structure soft foundation treatment,station bridge differences settlement,rapid filling and other high embankment soft foundation treatment segment with high technical and economic benefits,which promote the use of higher value.
