摘要
大跨度混凝土斜拉桥拆除风险高、难度大,以上海市叶新公路泖港大桥拆除施工为例,从挂孔梁、河跨标准主梁、主塔拆除3个环节对大跨度混凝土斜拉桥拆除施工技术进行研究,并总结拆除吊装施工过程中的安全控制要点及经验,可为今后类似工程起重吊装提供借鉴。
The demolition of long-span concrete cable-stayed bridge is high risk and difficult.Taking the demolition of Maogang bridge on Yexin highway in Shanghai as an example,the demolition construction technology of long-span concrete cable-stayed bridge is studied from the three points of hanging hole beam,river span standard main beam and main tower demolition,the safety control points and experiences in the demolition and hoisting construction process are summarized,which can provide reference for the hoisting of similar projects in the future.
