内蒙古达拉特地区挤扩支盘桩使用效果分析

摘要

通过对内蒙古达拉特旗地区施工的挤扩支盘桩和后压浆钻孔灌注桩的承载力及变形进行了分析,并结合两种桩型施工工艺和经济效果,对同一地质条件下两种不同成桩工艺进行分析比较,为该地区桩基设计及施工提供指导。%The paper analyzes the bearing capacity and deformation of the squeezed branch pile and post grouting bored pile in the construction of Daladateqi region of Mongolia,and analyzes and compares two kinds of piling techniques under the same geological condition by combining with their construction technology and economic benefits,which has provided certain guidance for the pile foundation design and construction in the region.
