摘　　要：猫道是悬索桥上部结构施工最重要的高空作业通道和场地,其线形、结构安全、抗风稳定性将影响整个上部构造施工各个主要分项工序的质量、进度和施工安全。猫道承重索是猫道结构的主要受力体,通常采用捻制的钢丝绳制作,在泰州大桥上部结构施工中,对于重复利用的猫道承重索钢丝绳,参照国内相关规范制订了完善的检验方案,对确保施工猫道的结构安全、降低施工成本,具有良好效果,对国内猫道钢丝绳的重复使用具有积极的借鉴意义。cat-walk is the most important passage and place for working at high altitude in the construction of suspension bridge superstructure, and its profile, structural safety and anti-wind stability are related to the quality, progress and work safety of all main work sections in the construction of the whole superstructure. The load beating cables are the main load-bearing components in cat-walk structure, usually made of twisted steel wires. In the construction of superstructure of Taizhou Bridge, for the cat-walk load bearing cable wire ropes for repeated use, complete inspection plan is formulated with reference to relevant specification in China, with good effect in ensuring the structural safety of constructing cat-walk and lowering construction cost, and this is of positive significance to the repeated use of cat-walk wire ropes in bridge construction in China.
