摘　　要：在万银国际大厦基础设计中,主楼部分采用基础变刚度调平设计原则,对桩和筏板进行了优化设计,对桩的持力层和类型进行了合理选择。分析了后注浆对持力层压缩模量等物理性能及桩刚度的改变。采用JCCAD软件对主楼与裙房基础间差异沉降进行计算,与现场沉降观测结果进行了对比。In the foundation design of Wanyin International Mansion,adjusted foundation rigidity design was adopted for reducing different settlement,and optimum design for piles and raft plates was used.Supporting course and type of piles were selected.Transformation of compressive modulus and pile-stiffness by post grouting was analyzed.Different settlement of main building and the podium was calculated by JCCAD and field measurement result was compared.

关 键 词：桩筏基础 后注浆 压缩模量 差异沉降
