摘要
在钢管混凝土系杆拱桥系梁施工过程中,施工支架的承载能力和稳定性是工程的关键。本文以庐铜铁路上跨S321省道特大桥为例,对上跨公路系杆拱桥系梁施工支架设计、门式支架建模、安全检算进行了简要阐述。
Construction frame's bearing-capability and stability of collar beam is the key points in the construction of the through supported steel pipe concrete tied arch bridge.In this paper,Lujiang-Tongling Railway across S321 Province special bridge as an example,construction frame's designing of collar beam,modeling of portal frame,safety checking are briefly introduced.
