摘要
文章根据甘肃省庆阳市高庄桥的病害调查,分析了产生不同病害的原因,提出钢筋混凝土套箍封闭主拱拱肋、黏贴钢板加固主拱拱肋和活性微粉混凝土(RPC)套箍封闭主拱拱肋三种加固方案,并对拱桥加固前后的结构进行有限元分析,论证三种加固方案对拱桥的应力改善效果。
According to the defect investigation of Gaozhuang Bridge in Qingyang,Gansu,the article analyzes the different causes and proposes three reinforcement plans such as using reinforced concrete,attaching steel board,or using active RPC to seal off the arch.It also performs finite element analysis on the bridge structure before and after the reinforcement to demonstration of the effects.
