摘　　要：将超高层建筑空间巨型框架结构与其基础等效连续化为一个半无限大弹性地基上的加劲薄壁筒组合体,并以此三维模型,用半解析法分析计算了受静力作用的超高层建筑空间巨型框架结构与其基础地基的共同工作。通过计算结果分析,得出了一些很有价值的结论。The spatial mega-frame structure and its foundation of a super tall building are simplified equivalently and continuously into a three-dimensional model, which is a combination of stiffened thin-walled tubes on semi-infinite elastic subgrade. The interactions between semi-infinite elastic subgrade and spatial mega-frame structure of a super tall building space-mega-frame structure under static loads are computed and analyzed with the three-dimensional model by senti-analytical method based on ODE （Ordinary Differential Equation） solver. A numerical example is given to verify the effectiveness of the model. Some valuable conclusions are drawn from the results of the numerical example.
