摘　　要：为探究沿江桥立柱腐蚀灾害成因,以及如何对其进行灾害处置,论文依托某实际运营沿江桥梁工程,对沿江桥墩柱腐蚀病害的原因进行了分析,结合有限元软件对于桥墩加固前后的承载能力进行分析,同时对病害桥梁墩柱采用“补强钢筋+钢护筒”的增大截面法加固设计方案以及加固施工关键技术进行分析。In order to explore the causes of column corrosion disaster of bridge along the river and how to deal with it,based on the actual operation of a bridge project along the river,the causes of the corrosion disease of the pier columns along the river are analyzed.Combined with the analysis results of the bearing capacity of the pier before and after reinforcement with finite element software,the reinforcement design scheme of the increased section method of"reinforcing steel bar+steel casing"for the pier columns of the diseased bridge and the key technology of reinforcement construction are studied.
