摘要
应用有限元法研究了CFG桩复合地基[1]在水平和竖向荷载作用下的工作性状。分析了不同褥垫层厚度、不同水平力大小时CFG桩复合地基的工作性状。结果表明:相同水平力作用下,褥垫层厚度越大桩顶水平位移越小;褥垫层厚度存在一个合理的范围以使承台的水平和竖向位移较小。
The behavior of CFG pile composite foundation under horizontal and vertical loads was by using finite element method. It was analyzed that the effects of different cushion thicknesses and hori-zontal loads on the behavior. The results show that the horizontal displacement of pile top decreases when the cushion thickness increases under the same horizontal load; there is a reasonable range for cushionthickness to make horizontal and vertical displacement of the foundation small.
