摘要
由于性能退化及整体刚度不足,部分旧桥出现桥梁振动剧烈的情况.这种情况严重影响了桥梁的通行舒适性,因此,不得不采取减振加固措施.鉴于目前我国尚无公路桥梁振动舒适性评价的相关规范,文中引入日本VG指标和ISO263-1-1997国际标准,对一座钢管混凝土拱桥进行舒适性评价,对比了两种评价方法的相关性,并有针对性地提出加固设计方案.通过对加固前后桥梁振动舒适性的对比,验证了加固方案的有效性.
Due to the degradation of performance and insufficient overall stiffness, some old bridges have severe vibration, which seriously affects the traffic comfort of bridges. Therefore, vibration reduction and reinforcement measures have to be taken to solve the problem. In view of the fact that there is no relevant standard for evaluating the vibration comfort of highway bridges in China, this paper introduced Japanese VG index and IS0 263-1-1997 international standard to evaluate the comfort of a concrete filled steel tubular arch bridge. The correlation between the two evaluation methods was compared, and the reinforcement design scheme was put forward. By comparing the vibration comfort of the bridge before and after reinforcement, the effectiveness of the reinforcement scheme is verified.
