摘要

破坏性地震使交通系统严重毁坏,地震造成的交通中断使生命财产遭受巨大损失。地震灾害的沉痛教训不断地警示着世人,使人们对桥梁的抗震研究工作逐渐受到重视,桥梁抗震理论及技术水平日渐提高。该文介绍了目前用于桥梁抗震设计的几种主要分析方法,包括静力法、反应谱法、动力时程分析法,为在今后的抗震设计中选择合适的设计方法提供了依据。
The destructive earthquake makes the transportation system seriously destroyed.The interrupted transportation induced by earthquake will enlarge loss of parasitic infestation.Lessons of earthquake damage have taught the people to make the research on the seismic design of bridges be recognized gradually.Consequently,the methodology and technology about seismic design are improved.The article introduces several analysis methods of bridge earthquake resistant design including static method,response spectrum method and dynamic time-history analysis,which are helpful for the selection of suitable design methods for the earthquake resistant designs.
