摘要
随着悬索桥跨度在不断地刷新记录,主缆索股数量多,猫道承重索长,这就要求猫道架设及主缆架设牵引系统能够提供足够大的牵引力,运行速度快且系统稳定,为悬索桥上部结构施工提供动力源。牵引系统对于悬索桥而言尤为重要,论文结合襄阳庞公大桥项目,系统地介绍三塔地锚式悬索桥牵引系统的设计及施工技术,成功解决了多塔大跨度悬索桥对牵引系统的高要求难题,为同类型项目提供技术支持。
As the suspension bridge span continues to set new records,the number of main cable strands and the length of the catwalk load-bearing cable require that the catwalk erection and the main cable erection traction system provide sufficient traction,speed and stability of the system,to power the construction of the suspension bridge superstructure.Traction system is particularly important for suspension bridges.This paper introduces systematically the design and construction technology of traction system for three-tower ground-anchored suspension bridges in combination with the Panggong Bridge Project in Xiangyang,it has successfully solved the problem of high demand for traction system of multi-tower long-span suspension bridge,and provided technical support for similar projects.
