用于垂直分段施工的拱桥下承式挂篮研究

Research on Bottom-supported Hanging Basket for Perpendicular Sections of Arch Bridges

针对重庆礼嘉嘉陵江大桥的下弦钢筋混凝土拱桥施工项目,对节段垂直分缝的下承式施工挂篮的关键技术进行研究,并对挂篮的结构进行有限元分析,为类似拱桥的施工挂篮设计提供参考。

Aiming at the construction project of the bottom-chord reinforced concrete arch bridge of the Lijia-Jialing River Bridge in Chongqing,this paper studies the key technologies of the bottom-supported hanging basket for perpendicular sections of arch bridges.The structure of the hanging basket is analyzed by finite element,which provides a reference for the design of the construction hanging basket similar to the arch bridge.
