摘　　要：本文首先分析了影响悬索桥主缆线形的各种因素 ,然后采用精确的悬索桥缆索系统分析程序 ,对两座典型悬索桥的主缆线形进行了计算分析 ,比较了成缆空缆状态与基准索股空缆状态 ,得出了一些有意义的结论 ,供设计和施工时参考。Factors that affect the cable shape of suspension bridge are studied. Using an exact analysis program of cable system, the cable shape of two typical suspension bridges are calculated, and comparison is made between cable finish stage of whole cable and of datum strand. Some useful conclusions are obtained for references in the design and construction of suspension bridges.
