摘　　要：通过对几种确定斜拉桥成桥合理索力方法的分析比较,发现每一种方法都有优缺点.单独使用某一种方法难以得到合理的索力值.以彭溪河大桥为背景,介绍了一种确定成桥合理索力的综合方法,实例证明此法是有效的.By analyzing and comparing some methods for determining the reasonable tension in the completion state of cablestayed bridge,that there are respective merits and demerits of each method are put froward. The unreasonable results are often deduced only in one way. A comprehensive way to determine reasonable cable forces is introduced by the example of the Pengxihe Brldge,and the method proved to be valid.
