摘要
本文通过对Ｄ．Ｈ．Ｇｅｉｇｅｒ提出的索穹顶结构几何特性的分析，最终给出了保证所有的索都处于张力状态而无松弛的条件，即索穹顶结构具有稳定性的条件。同时，给出了具有物理意义的所有非伸缩性变形模式位移基向量，可作为设计索穹顶结构的基础理论和方法，此分析同样适用于其它类型的索穹顶结构稳定性分析。
Abstract In this paper, according to the analysis of the structural geometric behavior of a class of tensegrity domes which has been proposed by D.H.Geiger, the author presents the condition of making all cables tensing and no slackening, i.e. the condition of stability of tensegrity domes. Meanwhile, all displacement vectors of inextensional modes of deformation which have obvious physical significance are derived. This method can be used as basic theory of tensegrity domes design and be applied into the stability analysis of other types of tensegrity domes.
