| 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. |
