摘要
跨中下挠过大是大跨径连续刚构桥常见病害之一,以吉茶高速公路的一座55 m+100 m+55 m的连续刚构桥为实际工程背景,对大跨度连续刚构桥长期下挠的主要原因进行分析,得出一些有意义的建议和措施,以供参考。
Undue deflection at midspan is one of the common hazards on long-span continuous rigid-frame bridge.In this paper,several influence parameters on long-term deflection of long-span continuous rigid-frame bridge have been analysed,some suggestions and methods are given for reference.A continuous rigid-frame bridge with span arrangement 55 m＋100 m＋55 m on Hunan Province Jicha highway was selected as the engineering background.
