摘　　要：通过对束筒结构体系的叙述,建立三维半解析分析模型,将静力分析问题转化为常微分方程组边值问题,并利用常微分方程求解器进行求解,对其计算结果作了分析,得出最大应力、最大剪力及地基刚度的变化趋势。Through the narration of the bundled-tube structure system, the paper builds the three dimensional semi-analytical model, transforms the static analysis problems to the boundary value problems for the ordinary differential equations, and gets the equations solution by using the ordinary differential equation solver, analyzes the calculation results, obtains the change trend of the maximum stress, the maximum shear force and the foundation stiffness.

关 键 词：超高层建筑 束筒结构 半解析方法 地基刚度
