摘要
在地基处理工程中,强夯法具有提高地基承载力、减小地基工后沉降、提升地基稳定性的作用,因而得到了广泛应用.文中依托华晨宝马第三工厂地基处理项目,进行室内土工试验与试验田工后沉降监测,通过Abaqus建立数值分析模型,改变夯击能、夯间距、夯锤直径,分析不同施工参数对强夯地基工后沉降的影响规律.
Abstract
In the foundation treatment engineering,dynamic compaction method has a good effect on improving the bearing capacity of the foun-dation,reducing the settlement of the foundation after construction,and improving the stability of the foundation,so it is widely used in the treatment of various kinds of foundation.Based on the foundation treatment project of BMW Brilliance Plant No.3,this paper conducts indoor soil test and post-construction settlement monitoring of experimental field.A numerical analysis model is established by Abaqus,and the influ-ence of different construction parameters on post-construction settlement of dynamic compaction foundation is analyzed by changing the tamping energy,tamping distance,tamping hammer diameter.
