现浇箱梁跨城市道路门洞的设计及施工

Study on the Design and Construction of Gateway Openings for Cast-in-Situ Box Girders across the City Road

文章结合某桥梁工程的施工,对现浇连续箱梁跨城市道路的门洞支架进行了设计,并着重对门洞支架的强度、刚度及稳定性进行了验算以确保工程施工的安全,同时阐述了门洞支架搭设的施工要点,为类似工程施工提供了借鉴。

This article, combined with the construction of a certain bridge, attempts to design the gateway opening support for Cast-in-Situ Box Girders across the city road, stressing the calculation of its intensity, rigidity and stability to ensure the safety of the construction. In addition, this article introduces the key points for construetion.
