摘　　要：随着城市交通的发展,曲线梁桥成为不同道路互联互通的首选桥型。曲线梁桥独特的受力特点易造成桥梁出现支座脱空、伸缩缝破坏、墩柱开裂等横向爬移引起的病害。文章在总结分析常见病害及原因的基础上,从主动与被动影响因素两个方面分析了不同因素的影响原因及程度,并对新桥的设计和运营桥梁的加固设计提出了相应的预防与加固对策,可为后续曲线梁桥设计与加固提供一定的指导。With the development of urban transportation,curved beam bridges have become the preferred bridge type for interconnecting different roads.The unique stress characteristics of curved beam bridges can easily cause lateral crawling diseases,such as bearing detachment,expansion joint damage and pier column cracking.On the basis of summarizing and analyzing the crawling diseases and their causes,the influencing reasons and degrees of different factors from both active and passive perspectives were analyzed.And the corresponding prevention and reinforcement measures for the new bridges design and the reinforcement design of operational bridges and were proposed.The research results of this article can provide certain guidance for the new design and reinforcement countermeasures of curved beam bridges in the future.
