摘要
本文通过对高层空间剪力墙结构采用双重扩大子结构有限元分析，同时采用弹塑性地基模型，对高层建筑与地基共同作用进行了综合分析。通过对上海一幢有代表性的高层建筑的的大量模拟计算，探讨了空间剪力墙与地基基础共同作用的机理和全过程，研究了上部结构刚度对基础的贡献、基底反力分布以及地基变形的变化规律。并将计算结果与实测结果作了比较。
In this paper, the result of the study on interaction between tall spatial shear wall structure and foundations has been presented. The spatial shear wall structure is analyzed by using the double extended substructure finite element method and the I'oundation soil by elastoplastic stress--strain model. In order to study the mechanism of structure--soil interaction such as the contribution of the superstructure to foundation stiffness, the distribution of contact pressure and the variation of settlement,quite a number of comparisons between the computed and measured results has been studied in this paper.
