跨路口现浇箱梁门洞支架设计及计算

Design and Calculation of Cast-in-place Box Girder Door Hole Bracket Across the Intersection

城市高架桥梁的施工中经常会以现浇箱梁方式跨越通过路口的情况。根据交通组织需要,部分路口保障既有道路行车安全畅行是施工中关注的重点。论文通过工程实例,进行跨路口现浇箱梁门洞支架的设计及计算,为类似施工情况提供参考。

In the construction of urban elevated bridge,it is often used to cross the intersection by cast-in-place box girder.According to the needs of traffic organization,it is the focus of the intersection to ensure the safety of existing roads in the construction.In this paper,the design and calculation of the cast-in-place box girder door hole bracket across the intersection are carried out to provide reference for similar construction situations.
