城市桥梁安全事故多发,导致墩柱产生不同程度的破坏,为快速恢复交通,保障城市道路的畅通,有必要对桥梁结构的应急检查和应急加固措施进行研究。本文总结了设置支撑、增大截面、钢套管、纤维增强材料(FRP)和绕丝五种针对墩柱损伤的加固措施;重点关注了各措施的加固效果、适应条件、处置时间和对现状交通的影响;总结了各措施在用于城市桥梁墩柱应急加固中的优缺点。 Multiple accidents of urban bridges lead to different degrees of damage to the piers. In order to quickly restore traffic and ensure the smooth flow of urban roads, it is necessary to conduct an emergency inspection and emergency reinforcement measures for bridge structures. This article summarizes the reinforcement measures of five kinds of pier damage, such as support, increasing section, steel casing, fiber reinforced material (FRP) and wound wire, and focuses on the reinforcement effect, adaptability conditions, disposal time and the current situation Traffic impact; summarizes the advantages and disadvantages of each measure in the emergency reinforcement of city bridge piers.
