摘要
介绍了某大桥立柱及盖梁因外力刮擦桥墩出现裂缝等病害而进行加固的工程实例。论述了该大桥立柱及盖梁的病害情况,制定了相应的加固处理方案。针对该大桥桥墩立柱及盖梁的具体病害,进行加固方案论证并确定最佳的加固方案,选择最为经济合理的加固方法——立柱裂缝注胶扩大截面、盖梁黏贴碳板。经加固处理后,大桥立柱及盖梁使用良好,达到预期效果。
This paper introduces a reinforcement engineering case of a bridge pier column and beam due to external scratching cracks and other diseases. Discuss the disease of the bridge column and beam, formula- ted the corresponding reinforcement scheme. According to the disease of the bridge pier column and beam, demonstrate and determine the best reinforcement scheme for strengthening scheme, Choose the most eco- nomical and reasonable reinforcement method-column crack expansion section and glue paste carbon plate beam. After strengthening treatment, The column and beam bridge is well, it achieve the desired effect.
