摘要
马鞍山长江公路大桥猫道形式为四跨连续无抗风缆构造,对左汊悬索桥的猫道结构和安全设计以及整个施工过程进行研究。结果表明,通过增加横向通道取消抗风缆,既能保证整个猫道架设和使用的安全,同时减小猫道架设的难度,提高猫道架设进度,为其他多跨悬索桥猫道施工提供借鉴。
The catwalk structure of Maanshan Changjiang River Highway Bridge is a continuous structure of four spans and without wind cable structure. This paper conducts a study on the structure and security design and whole construction process of the catwalk for construction of the south suspension bridge. The results show that increasing of cross bridges and cancelling of the wind ropes, which can ensure the catwalk erection and use safety, and reduce the difficulty of catwalk erection, im omve the catwalk erection progress, provide a reference for other muhisnan susnension hrlde construction.
