摘　　要：主缆是悬索桥的重要受力构件,精确计算其空缆线形是悬索桥上部结构施工成败的关键。采用有限元软件ANSYS分析其空缆线形,得到的计算结果满足设计要求,得出了用ANSYS分析大跨度悬索桥主缆空缆线形可为设计和施工提供技术依据的结论。The cable is the important component of suspension bridge. Determination of initial states of cable of large span suspension bridge is the key part of the upper structure construction. Through finite element＇s analysis of initial states of cable with ANSYS software and comparison between the calculating results with design values, it can be concluded that analyzing cable＇s initial state with ANSYS software matches design requirements closely and can be used as large span suspension bridge cable analysis. Its calculating result may offer technology reference for the designer.
