温度效应对主缆设计和施工有重要影响。在已有研究基础上，推导了分析主缆非均匀温变场问题的解析方法，其中的温度和静力应变均以无应变状态为参考态并考虑了主缆变形前后截面的变化，在理论上较已有方法更为合理，算例表明了其正确性。

Temperature effect plays an important role in the design and construction of suspension bridge main cables.A new analytical method of non-uniform variable temperature fields was derived by considering the non-uniform variable temperature fields of the main cables,i.e.the temperature and static load were treated as unstressed state,while considering the crosssection variations pre-and post-deformation of the main cable.The method is theoretically more rational,which is verified via an example.
