大节段现浇变截面连续转体梁桥设计

摘要:

跨沪蓉高速公路变截面连续转体梁在设计阶段统筹工期、实际条件等因素，探索通过调整钢束布置形式，改变锚固位置，设计与施工互相匹配，进而达到采用支架大节段现浇，缩短工期，节约工程费用的目的。

Abstract:

In the design stage of variable cross-section continuous concrete bridge overpassing Shanghai Chengdu Highways, the construction period, On-site Construction and other factors are planned as a whole. Through adjusting the layout form of steel strand, changing the anchorage position, and matching the design and construction, the purpose of adopting large segment cast-in-place support, shortening the construction period and saving the engineering cost is achieved.
