Abstract

Abstract: A new strengthening technical solution for the reinforced concrete arch bridge was put forward． The train of thought，method and construction of the prestressed reinforced concrete arch bridge was elaborated firstly． Then，the principle of reinforcement and calculation points was discussed． Finally，a bridge was analyzed and calculated by the large scale simulation software Midas Civil before and after reinforcement． The calculation and analysis results show that the proposed reinforcement method has the advantages，such as，good results，high social benefit，simple to handle and economize．

Key words: innovation, prestress, strengthen, reinforced concrete bridge

摘要： 创新性的提出了钢筋混凝土拱桥的一种新的加固技术方案。首先对体外预应力加固钢筋混凝土拱桥的思路、方法、施工工序进行了阐述，进而对加固的原理、计算要点做了说明，最后通过MidasCivil大型仿真分析计算软件对某桥加固前后进行了分析计算。分析结果表明:提出的体外预应力加固钢筋混凝土拱桥的新加固方法具有加固效果好、社会效益高，简便、经济等优点。
