摘要/Abstract

摘要： 介绍了钢筋混凝土斜腿刚架拱桥的病害.采用桥梁结构分析软件建立了结构分析模型.通过计算分析明确承载力安全度较低的部位,提出湿接钢板法及普通粘钢板法加固桥梁的方案;通过复核计算证明了加固设计的可行性及合理性.

关键词: 桥梁结构；斜腿刚架拱桥；加固设计；

Abstract: This article presents the deteriorations of the concrete frame arch bridge with slant leg.The model for structural analysis is built by using a bridge analytical software.The lower security position is located by structural analysis.The reinforcement methods of humid-plastering steel plates and ordinary-plastering steel plates are proposed for different positions.The reinforcement design is proved feasible and reasonable by rechecking calculations.

Key words: bridge structure； frame arch bridge with slant leg； reinforcement design； structure analysis；
