摘要
大桥加宽是交通发展所面临的新问题,无论采用单侧或双侧加宽,均存在新、旧桥之间的衔接问题,本文所述的是新、旧桥采用分离设计,且用柔性桥面纵向缝的设计方案。
The widening of extra-long bridges is a new challenge faced by the transportdevelopment. No matter what method is adopted, bridges are widened either from one side or both sides ofbridges, the connections between old and new bridges are a problem. The separation design for new and oldbridges and the design for bridge deck longitudinal joints are introduced.
