摘要
新建嘉陵江大桥-支线桥梁跨既有宝成铁路采用2x35m先简支后连续预制小箱梁,具有结构形式简单、施工方便、迅速等优点。论文概要介绍了上、下部结构构造、结构计算分析及施工方案。通过本桥设计,为今后上跨铁路桥梁设计积累了有益的经验,对类似桥梁设计有一定的参考价值。
The new-builting Jialing River Bridge-branch of across existing Bao-Cheng Railway put to use 2x3 5m simply supported continuous precast small box girder,which has simple structure,convenient construction,has the advantages of rapid.This paper briefly introduces the calculation analysis and construction scheme.Through this bridge design,for the future of crossing railway bridge design accumulate useful experience,have certain reference value to the similar bridge design.
