摘要
桥梁作为交通生命线的枢纽工程,一旦遭受地震破坏,将会导致巨大的经济损失,并影响震后灾区的救援和重建工作,使得人们对桥梁的抗震性能越来越重视。桥梁抗震性能研究主要有两个方面,一是对新建桥梁采取合理的抗震设计和抗震构造措施;二是对现役桥梁的抗震加固。本文介绍了国内外在桥梁抗震加固方面的一些研究成果,并对桥梁抗震加固的方法进行了总结和评述,以期对我国现役桥梁的抗震加固提供一些参考和借鉴。
Reducing the damage of bridges is one of important parts of reducing and preventing disaster of transportation lifeline, in earthquake, spectacular failure of bridges will lead to traffic system intermitting, cause tremendous losses of property and affect rescue work after earthquake. Seismic performance of bridges is widely paid attention to in recent years. There are two aspects about seismic performance of bridges. One is the reasonable seismic design and the corresponding constructional measures. The other is seismic retrofit for the existing bridge. Some seismic retrofit methods are summarized and reviewed out in this paper, which can be reference for bridge engineers and researchers.
