Abstract:
The incremental launching project of south side bridge of Amro highway Yellow River Bridge is a 100m long-span continuous steel girder jacking project, a new wind-resistant steel guide beam is designed. Optimizing the steel guide beam which can meet the requirements for the incremental launching and Anti-typhoon requirements in non-working state by finite element structural analysis. It has great research value on the incremental launching of large-span steel beams.
安罗高速黄河特大桥南副桥顶推工程为100m 大跨连续钢梁顶推工程,设计一种大跨度钢梁顶推抗风钢导梁,通过有限元结构分析对钢导梁结构进行优化, 既能满足顶推施工需求,也能满足非工作状态下抗台风需求,对大跨钢梁顶推具有较大的研究价值。
