摘要:近年来独柱墩桥梁倾覆事故时有发生,通过对独柱墩桥梁抗倾覆性能进行验算,发现众多独柱墩桥梁不满足现行规范的抗倾覆性能指标要求,需大范围对独柱墩桥梁抗倾覆性能进行排查和加固改造。从独柱墩桥梁倾覆问题的特点及原因分析,桥梁抗倾覆性能验算评估方法及桥梁倾覆机理,独柱墩桥梁加固改造技术解决方案以及独柱墩桥梁运维要点等方面进行全面梳理和研究,为独柱墩桥梁的安全运营提供全面的技术指导。

Abstract: In recent years, many single column pier bridges can not meet the anti-overturning performance index requirements of the current latest specifications under the background of single column pier bridge overturning accidents, through checking the anti-overturning performance of single column pier bridge. Therefore, the investigation and reinforcement of anti-overturning performance of single column pier bridge on a large scale emerge as the times require. The characteristics and causes of single column pier bridge overturning problem are analyzed, the bridge anti-overturning performance checking evaluation method and bridge overturning mechanism, the technical solutions of single column pier bridge reinforcement and transformation, and the key points of single column pier bridge operation and maintenance are comprehensively studied, so as to provide more comprehensive technical guidance for the safe operation of single column pier bridge.
Keywords: bridges; single column pier; anti-overturning; reinforcement and reconstruction
