钢筋混凝土双曲拱桥广泛修建于上世纪70年代,目前桥梁病害严重,承载能力降低,对行车安全构成了严重的威胁.分析既有钢筋混凝土双曲拱桥的病害,并指出了病害产生的原因,根据双曲拱桥的结构特点和病害特征,研究了双曲拱桥的粘贴维修加固措施.并以一座实际桥梁为工程背景,将粘贴维修加固措施应用到实际当中.通过加固前后桥梁抗力的对比可知,所提出的维修加固措施对双曲拱桥是非常有效的.
鋼觔混凝土雙麯拱橋廣汎脩建于上世紀70年代,目前橋樑病害嚴重,承載能力降低,對行車安全構成瞭嚴重的威脅.分析既有鋼觔混凝土雙麯拱橋的病害,併指齣瞭病害產生的原因,根據雙麯拱橋的結構特點和病害特徵,研究瞭雙麯拱橋的粘貼維脩加固措施.併以一座實際橋樑為工程揹景,將粘貼維脩加固措施應用到實際噹中.通過加固前後橋樑抗力的對比可知,所提齣的維脩加固措施對雙麯拱橋是非常有效的.

Reinforced concrete double-curved arch bridges were built aboard in 1970s.The damage of them becomes so severe at present.The loading capacity of them is reduced, which threatens driving safety greatly.In this paper,damages of bridge are summarized,and then damages causes are pointed out,reinforcement measures of bridge are studied basing on structure characteristic and damages features and applied to bridge structure basing on an existing bridge.After the comparison of the parameters of the resistance before and after the reinforcement,the reinforcement measure to the bridge is showed to be effective.
