摘要
阐述了石拱桥的加固方法。以某空腹式块石拱桥的同心桥为例,针对其病害提出了该桥的整治加固措施;然后运用有限元软件M idas和现场荷载试验的方法对同心桥的承载特性进行分析与评估。加固后,该桥的结构承载力能够满足设计荷载标准(公路-Ⅱ)的要求。
The main reinforcement project of stone arch bridge is introduced. With a certain tongxin bridge built with an empty block-stone arch bridge as an example, a thorough test of the bridge is made and the reinforcement measures of the bridge are put forward. Analysis and evaluation of load-bearing characteristics of tongxin bridge are made with finite element software Midas and the load test on site. After the reinforcement, the structure carrying capacity can meet the needs of design load standard （ Highway Ⅱ）.
