摘要
独柱墩桥梁横向稳定性较差,易发生整体倾覆事故.基于此,文章结合锦龙立交A匝道桥第9联桥实例,通过对设计原理的分析,提出具体的加固措施及现场施工难点应对措施,同时对维修后的日常养护提出具体建议,希望为今后该类型桥梁加固及养护工作提供参考和帮助.
Abstract
The lateral stability of single-column pier bridge is poor,and it is prone to overall overturning acci-dent.Based on this,combined with the example of the 9th joint bridge of Jinlong interchange A ramp bridge,through the analysis of the design principle,this paper puts forward specific reinforcement measures and countermeasures to deal with on-site construction difficulties,as well as spe-cific suggestions for the daily maintenance after repair,hoping to provide reference and help for the reinforcement and maintenance of this type of bridge in the future.
