摘要： 温度对悬索桥的线形有较大的影响,在悬索桥空缆架设施工中,温度不仅改变主缆索股的长度,而且将引起主塔的偏位,这些都将导致主缆线形的改变.文中分析了主缆线形温变影响以及在此基础上,提供了计算主缆线形和主塔偏位的程序设计,并以实例加以说明,可供桥梁施工技术人员参考.

Abstract: Temperature have comparatively big influence on the empty cableshape of suspension bridge,durning the building of the empty cableshape,temperature play the roles that not only changing the length of the cable,but also causeing the deflextion of the main tower,and both of them lead the changing of the cableshape. In this thesis,I analyse the temperature influnce on the cableshape, and based on this, I provide the designed programes for counting the cable shape and the deflexion of the main tower,with examples and instruction, as reference for technicians of bridge building.

Key words: suspension bridge, empty cable shape, temperature
