| 摘 要： | ＣＦＧ桩复合地基是一种新型的软弱地基处理方法。本文结合具体工程并进行了有限元分析，探讨了这种复合地基在垂直荷载作用下的变形、强度以及碎石褥垫层、桩身刚度变化、置换率对地基加固效果的影响，并用实地载荷试验进行了验证，肯定了有限元分析的合理性。

| Abstract: | CFG pile composite foundation is a new ground improvement method for soft clay.In this paper,with a practical engineering project,the strength tests in lab for the pile itself were done,and the strength and deformation of the composite foundation under the vertical loading are analysed and discussed by using the nonlinear finite analysis.The main factors affecting reinforcement result,such as broken stone cushion,an area ratio of column to soil and change of column rigidity are studied.Loading tests in site proved further the feasibility of this numerical analysis method. |
