摘要
CFG桩复合地基是一种新型的软弱地基处理方法,通过对桩土应力比与褥垫层厚度的关系的有限元分析,并采用CFG桩复合地基中设置不同厚度褥垫层的方法,得到了褥垫层作用下桩土应力比的分布规律,此分布与理论分析一致。该研究为复合地基褥垫层厚度的设置及复合地基优化设计提供了依据。
CFG pile composite foundation is a new ground improvement method for soft clay. In this paper, the finite element analysis of the relationship between the thickness of the cushions and the pile -soil stress ratio is analyzed, And the method are conducted with setting the cushions of different thickness. The influence of the thickness of the cushions on the pile - soil stress ratio is then studied. The research in this paper will provide a theoretical evidence for a suitable selection of the thickness of the cushion and an optimal design for the composite foundations.
