挂篮施工时宽幅混凝土箱梁横向框架的受力分析

Analysis on Stress of Transverse Frame of Wide Concrete Box Girder in Form Traveller Construction

摘要:

以府河大桥主桥70+120+70（m）预应力混凝土连续梁为背景，对挂篮施工过程的箱梁横向框架进行了受力分析。结合分析结果，对大跨径、宽幅预应力混凝土连续梁结构设计提出了一些建议，为以后同类型桥梁设计提供参考。

Abstract:

Based on the 70 m+120 m+70 m pre-stressed concrete continuous girder of Fuhe River Bridge, the stress of transverse frame of the box girder in the form traveller construction is analyzed. Combined with the analysis result, some suggestions are proposed for the structural design of long-span wide pre-stressed concrete continuous girder, which provides the reference for the design of the similar bridges in the future.
