摘　　要：针对工程设计中上部主楼层数相差较大、荷载分布很不均匀的情况,采用变刚度调平技术,通过控制桩刚度使上部结构荷载效应与桩刚度相匹配,有效减小基础的差异变形。In view of the large difference in the number of floors of the upper main building and the uneven load distribution in the engineering design, the variable stiffness leveling technology is adopted to match the load effect of the upper structure with the pile stiffness by controlling the pile stiffness, so as to effectively reduce the differential deformation of the foundation.

关 键 词：变刚度调平 桩刚度 差异变形
