摘　　要：本文在讨论《建筑抗震设计规范》抗震设防标准的基础上，结合公路桥梁的特点，把工民建结构的先进抗震设防原则推广到公路桥梁设计领域，根据公路等级和桥梁的规模大小，建议将桥梁的重要性分为四个等级，并运用概率方法分析确定了公路桥梁的三级设防标准及设计地震动参数，供规范修订的参考。The paper generalized aseismatic fortify principal of civil building to the fieldof road and bridge construction, on the base of discussing aseismatic fortify standard of'specification of Building Aseismatic Desian',and combinig with characteristics of road andbridge. According to road grade and bridge scale,the importance of bridge should be dividedinto four grade,and three classes of fortify standard was confirmed with probability method,for reference.
