斜腿刚架拱桥加固结构分析
Structure Analysis for Frame Arch Bridge with Slant Leg Before and after Strengthening
【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.
【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.
