摘　　要：给出了基于APDL语言的悬索桥索股无应力长度求解方法和桥梁结构的Ansys模型"无缝衔接",能快速准确地得出各索股的无应力长度。应用此方法,分析了影响自锚式悬索桥索股下料长度的各种因素,指导了某空间索面自锚式悬索桥主缆索股无应力索长的下料工作。This paper gives out a method to calculate the main cable＇s non-stressed length of suspension bridge using APDL language. It can give the main cable＇s non-stressed length quickly and accurately when it＇s used together with the bridge＇s Ansys model. With this method,various influence factors which have affect on the main cable＇s fabrication length of self-anchored bridge are studied,and the result was used in a space cable-net self-anchored bridge to get a accurate main cable＇s fabrication length.
