摘　　要：阐述了逆迭代法的基本过程与原理,并将其运用于预应力索结构的一类形状确定问题。逆迭代法不仅能确定索结构预应力初始态的预应力分布,而且能确定索结构零状态的几何。通过算例可看出此方法的精确性与广泛适用性。The principle of the inverse iteration method is stated and the method is applied to one kind of form-finding process. The method can determinate not only the stress distribution in pre-stress state but also the initial geometry of structure in initial state. Numerical examples show the high accuracy and the universality of this method.
