| 摘 要： | 首先给出了悬索结构的初态平衡方程，并提出了一种求解结构在初始态预应力分布的线性化方法，提出了的方法是以结构的预应力分布为未知量，而结构的几何外形由设计者给定，在预应力态确定的基础上，提出了一种如何由预应力态反算结构几何放样状态的方法，算例表有提出的方法是可行、实用的。

| Abstract: | In this paper the initial equilibrium problem for cable structures is firstly described and the linear solution method is then presented. The prestress distribution in the reference configuration which is explicitly defined by the designer can be effectively found by using the method of this paper. On the basis of the found initial equilibrium state, this paper presents a procedure for inversely searching the structure's geometry zero position. The sample results demonstrate that the methods of this paper is practicable and practical. |
