摘　　要：随着桥梁修建技术的发展,悬索桥的跨径不断增大。猫道作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、钢箱梁吊装、主缆防护等提供施工操作平台、材料及工具运输通道,从始至终贯穿整个悬索桥上部构造安装施工过程。以西江特大桥猫道作为研究对象,对其结构设计、施工过程及关键技术展开详细介绍,并对实际施工过程中出现的问题提出优化措施。With the development of bridge construction technology,the span of suspension bridge was increasing.As a necessary temporary structure for the construction of long-span suspension bridge,the catwalk provided construction operation platform,material and tool transportation channel for main cable erection,cable clamp and sling installation,steel box girder hoisting and main cable protection,which ran through the installation and construction process of the superstructure of the suspension bridge from beginning to end.Taking the catwalk of the Xijiang Grand Bridge as the research object,a detailed introduction was given to its structural design,construction process and key technology,and optimization measures were proposed for the problems that arised during the actual construction process.
