摘　　要：本文针对锥形单管塔这种空间薄壳结构进行了静力分析。比较了此种结构在设计荷载作用下非线性与线性计算的结果；获得了单管塔在风载作用下的荷载－位移曲线、极限承载力、失稳类型判定方法等，对同类工程的分析具有一定的参考意义。Static analysis of space thin shell structure is presented in this paper. The results of nonlinear theory of the pole under design loads are compared with the results of linear theory. The load-deflection curve of pole under wind load is solved based on the non-linear analysis. Then the ultimate capacity of the pole and the type of the instability are determined.

关 键 词：锥形单管塔 截锥壳 非线性 极限承载力
