Research on Disease Analysis and Reinforcement Method of Railway Bridge Pier
Taking Chifeng-Daban-Baiyinhua Railway bridge pier disease detection and repair and reinforcement engineering as the background,the on-site detection and theoretical calculation of railway bridge pier diseases are carried out,the causes of bridge pier diseases are analyzed,and the reinforcement design scheme is proposed by using glue injection and carbon fiber cloth comprehensive past-ing method according to the results of the analysis.After the reinforcement was completed and operated continu-ously for several years,the reinforced bridge piers were detected again,and the results show that there was no new disease in the bridge piers and no cracking in the original disease location.Practice has proved that the analysis re-sults of bridge pier diseases are reasonable and the rein-forcement effect is good,which can provide reference for the same kind of railway bridge pier maintenance engi-neering.
