铁路客专整体箱梁现浇支架大跨度门洞设计及施工关键技术

Design and Construction Key Technology of the Large-span Cast-in-place Support Door of Railway Passenger Double Dedicated Line Integral Box Girder

本文结合工程实例,详细阐述了采用碗扣式钢管架作为铁路客运专线双线整体箱梁现浇满堂支架及万能杆件与贝雷桁架组合设置大跨度铁路通行门洞的设计方案。并对支撑系统的主要承重结构进行了承载安全检算。以期能对其它类似项目的施工起到一些借鉴作用。

Combined with the engineering example, this paper introduces the design planning of large span railway traffic openings intercalated by the cast full support and universal bar and Bailey truss of the bowl-buckle passenger double dedicated line integral box girder. The safety inspection of main load-bearing structure of the support system is carried out to provide some reference for other similar projects.
