摘　　要：本文介绍了两阶段变刚度复合桩基的设计概念。应用ABAQUS有限元软件建立桩筏基础仿真模型,对两阶段变刚度复合桩基的工作机理分阶段进行了分析,验证了桩顶设置变形调节装置的复合桩基新技术的合理性。Abstract： In this paper the design concept for the two phases composite end - bearing pile foundation was introduced. The ABAQUS finite element method software was used to simulate the pile - raft foundation. The working mechanism for the two phases composite pile founda- tion was analyzed in different phases. It was verified that the new technology of composite pile foundation with a variable stiffness deforma- tion adjuster installed on the top of pile is reasonable. This research is with great value to the pile foundation design for buildings.
