桥梁结构在地震时遭到破坏,不但直接影响交通,而且往往引起次生灾害,加剧地震危害之严重性,修建在人口稠密地区和重要交通干线上的桥梁,更是如此。所以,桥梁的抗震是一件非常重要的工作。要作好桥梁抗震首先就要了解桥梁的震害和原因,为此本节专门比较细致的来介绍和分析国内几次地震中出现的桥梁震害。 Damage to the bridge structure during earthquakes not only directly affects traffic, but also often causes secondary disasters that exacerbate the magnitude of the earthquake damage. This is even more so for bridges built in densely populated areas and important transport links. Therefore, the earthquake resistance of the bridge is a very important task. To make the earthquake-resistant bridge First of all, we must understand the earthquake damage and the reasons for the bridge, this section is more detailed to introduce and analyze the bridge in several domestic earthquake damage.
