摘要
阐述了斜拉索腐蚀损伤的机理与影响因素,提出换索是去除桥梁病害并改善结构状态的重要手段。提出了斜拉索换索设计方法与要点,包括换索前状态评定、换索中结构分析及新斜拉索的设计。最后总结了斜拉索换索施工技术及注意事项,为斜拉索的更换设计与施工提供参考。
The mechanism and influence factors on cable corrosion and damage are expounded,which highlight that cable replacement is an important method to remove bridge disease and improve structural status. Design method and essentials on cable replacement are proposed,which include cable evaluation before replacement,structural analysis during replacement,and design of the new cable. Finally,the construction techniques and matters need attention are concluded,which could provide references for the design and construction of cable replacement.
