摘　　要：从新中国成立以来,我国桥梁抗震规范历经《地震区建筑规范草案》(1957年),《地震区建筑设计规范草案》(1964年),《公路工程抗震设计规范》(1977年)(试行),JTJ 004—89《公路工程抗震设计规范》,JTG/T B02-01—2008《公路桥梁抗震设计细则》。在随后多次修订中,不断继承和发展,逐步完善我国的桥梁抗震设计规范。2020年6月2日,交通运输部发布了JTG/T 2231-01—2020《公路桥梁抗震设计规范》,主要介绍2020版规范的修订情况,为广大工程设计人员更好理解该规范提供参考。Since the establishment of the P.R.C,the development of seismic code in China has experienced the Draft Code for Buildings in Seismic Areas(1957),Draft Code for Design of Buildings in Seismic Areas(1964),Code for Seismic Design of Highway Engineering(1977)(Trial),Code for Seismic Design of Highway Engineering(JTJ004-89)and Detailed Rules for Seismic Design of Highway Bridges(JTG/T B02-01-2008).In the subsequent revisions,it continued to inherit and develop,and gradually improved China′s bridge seismic design code.On June 2,2020,the Ministry of Transport issued the Code for Seismic Design of Highway Bridges,which mainly introduces the revision of the code,so as to provide reference for engineering designers to better understand the code.
