| 摘 要： | 目的 研究FRP修复震损钢筋混凝土管道的加固性能.方法 首先对预损伤钢筋混凝土管道进行破损加载,模拟中小地震中的损伤,然后内壁粘贴纤维增强复合材料进行加固.研究不同纤维材料加固下、不同损伤程度圆管三点试验的破坏特征、荷载应变关系和极限承载力.结果 FRP加固法可以改善管道的受力性能,延缓裂缝的开展速度,提高管道的极限承载力.碳纤维和玻璃纤维这两种材料的加固修复方法均非常有效.应用ANSYS有限元分析软件,建立了圆管三点试验有限元模型,给出了计算条件下的承载力极限值,并与圆管三点试验结果吻合较好.结论 受损试件加固后完全可以满足受损前的正常使用要求,并有所提高.此种加固修复技术,可供工程应用参考.
