摘要

采用ABAQUS有限元程序中的线性扩展D-P模型对带桩筏基下的地基土进行弹塑性模拟，建立了带桩筏基系统的ABAQUS程序三维有限元模型。经比较各种桩、筏基础的内力与沉降关系计算结果，得到了带桩筏基的一些工作特性。在此基础上结合《建筑地基基础设计规范》(GB5007-2002)，改进了传统的复合桩基设计方法，讨论了“三阶段”设计理念的可行性，并将其应用于工程实例。分析结果表明，改进的复合桩基设计方法和“三阶段”设计方法较常规设计方法更加经济合理。

Abstract

The soil under the piled raft foundation system was simulated by linear extended D-P elastic-plastic soil model. 3D finite element model of ABAQUS program was established to obtain some behaviors of the piled raft foundation system by comparison of load-settlement curves of several foundations. Composite pile foundation design method was studied and improved combined with Code for Design of Building Foundation (GB5007-2002)

then the three-stage concept was discussed. Computation results show that these two methods are more economical than conventional design methods.
