摘　　要：随着城市现代化建设的推进,城市跨线高架桥、快速路的建设越来越多,在桥梁的建设过程中,为不影响正常的交通进行,通常采用门洞+满堂支架的模式进行跨线现浇箱梁的施工。本文以单跨门洞为例重点介绍门洞受力验算的分析论证及施工重点控制点,以供同类工程参考运用。With the advancement of urban modernization construction, more and more urban over-the-line viaducts and expressways are being constructed. In the process of bridge construction, in order to not affect the normal traffic, it usually uses the mode of door openings and full supports for cast-in-place box beam construction. This article introduces the analysis and verification of the door opening force checking and the key control points of the construction with the single-crossing door opening as an example to provide the reference for similar projects.
