摘　　要：猫道为大跨径悬索桥施工必备的临时结构,为主缆架设、索夹和吊索安装、主缆防护等提供一个施工技术操作系统平台、材料及工具进行运输发展通道,从始至终贯穿整个悬索桥上部构造安装施工使用。本文以某跨越悬索桥为例,对猫道的设计及架设技术进行研究,对今后同类型工程有一定的参考作用。Catwalk is a necessary temporary structure for long-span suspension bridge construction. It provides construction operation platform, material and tool transportation channel for main cable erection, cable clamp and sling installation, main cable protection, etc., and runs through the entire suspension bridge superstructure installation and construction from beginning to end. This paper studies the design and erection technology of catwalk by taking the bridge of some span suspension bridge as an example, which can be used for reference for similar catwalk construction in the future.
