摘　　要：探讨了桥梁工程抗震设防水准与设防标准,提供了国内外桥梁抗震设计规范的相关规定,结合近年来桥梁抗震研究过程中的体会,建议采用重现期来描述设防水准,对于重大桥梁工程应采用多级设防的思想,建立设防水准与性能目标及设计指标之间的关系,明确设防标准。In this paper, the engineering are discussed and the fications for seismic resistance authors＇ research experiences i earthquake protection level and protection criterion for bridge relevant provisions in the domestic and foreign codes and specisign of bridge engineering are provided. With reference to the he seismic resistance design of bridge engineering in the recentyears, it is proposed that the return period should be used to express the earthquake protection level and for the important and major bridges, it is necessary to base the design of the bridges on the philosophy of multilevel earthquake protection, to establish the relation between the earthquake protection level and performance target and design indices, and also to make definite the earthquake protection criterion.
