| 摘 要： | 论述了高层建筑上部结构对箱形基础的影响，上部结构与基础共同工作，增加了基础的刚度，可以对基础的变形起制约作用；在高层建筑的设计中忽略了基础的变形和位移，人为地把基础和上部结构开计算，既不经济，也不安全，无原则要对建筑物进行整体的综合考虑，即应当考虑上部结构与地基基础的共同作用；上部结构的刚度是水平刚度、竖向刚度和搞弯刚度的综合，不但对基础产生影响，对地基反力的影响也很大，共同作用分析将使上部结构、基础和地基地内力和位移等方面与常规法相比均有显著的变化；对该领域目前所存在的问题进行了探讨。

| Abstract: | The paper aims to demonstrate the effect of upper structure on box foundation in tall structure, which can restrict the displacement of foundation since upper structure work together with foundation to increase its stiffness. Currently, the transmogrify and movement in box foundation are usually ignored by many people who device the tall structure. When they calculate, they separate the box foundation from upper structure instead of considering it as a combination. This is not safe and not economic either. The stiffness of upper structure includes horizontal stiffness, vertical stiffness and anti-interference stiffness, it affects not only box foundation but also its reaction. In practice, synthetic analysis has clear advantages in directing work which solve many problems. Finally problems which still unsolved in this field are discussed. |
