摘　　要：在桥梁建设中,斜拉桥作为大跨度桥梁的最主要桥型发展迅猛。斜拉索作为斜拉桥施工的关键工序,其制作、安装、张拉、索力调整等工艺复杂,施工难度及强度大且施工效率较低,介绍了某工程项目通过研发斜拉索施工辅助平台提高了斜拉索的安装精度、全桥同步张拉并结合相关的辅助与管理措施,极大程度地提高了大跨度斜拉桥斜拉索施工的效率及精度。In the bridge construction,the cable-stayed bridge,as the main type of long-span bridge,is developing rapidly.As the key working procedure of cable-stayed bridge construction,the manufacturing,installation,tensioning and adjustment of cable force are complex,difficult and strong in construction,and the construction efficiency is low,the project improves the installation accuracy and efficiency of stay cables through the development of an auxiliary platform for the construction of stay cables,which greatly improves the construction efficiency and precision of long-span cable-stayed bridge.
