摘　　要：以独塔自锚式悬索桥为对象介绍主缆成桥线形的分析理论.以分段悬链线理论为基础,给出主缆成桥线形的平衡关系和适合于独塔自锚式悬索桥主缆成桥线形分析的迭代方法,并编制相应程序.通过具体工程算例验证分析结果的正确性.Targeting self - anchored suspension bridge with single tower, the analysis theory of finished main cable shape is described. Based on the segmental catenary theory, the paper concludes the balanceness of finished main cable shape and the iterative method which has high explanation power in the scenario of self - anchored suspension bridge with single tower. The program also was accomplished. The calculation on the numerical sample of project was done to verify the accuracy of the result.
