预应力变截面连续梁挂篮设计及预压分析

Design and Deformation Analysis of Preloading of Hanging Basket for Pre-stressed Variable Cross-section Continuous Box Beams

以某大桥主桥变高度预应力混凝土连续箱梁为工程实例,讨论了该桥挂篮的设计与验算,并对该桥挂篮预压试验,表明该桥挂篮设计合理,可供类似工程参考。

Taking varying-depth prestressed concrete continuous box beam of a bridge as an example,this paper discussed design and checking calculation of hanging basket for the bridge.Then preloading test for hanging basket was conducted.The result indicated that the bridge hanging basket design was reasonable,which provided reference for similar projects.
