摘要:研究了CFG桩在粉土地基施工中出现钻孔真空后,由于水头差引起土体渗透变形的机理,分析了引起土体渗透变形的原因,提出了避免或减小此类因素的影响方法,给出了解决CFG桩在粉土地基施工中出现渗透变形问题的方案。
In this paper, the mechanism of Soil's deformation because of penetration caused by water level difference after CFG pile in silt appearing in the base of drilling vacuum is studied. The reason for Soil's deformation because of penetration is analyzed. Methods to reduce and avoid such impact are proposed. Schemes solving Soil's deformation because of penetration are given.
