摘　　要：在桥梁工程的抗震设计中,抗震设防标准是必须首先解决的问题。本文探讨了桥梁工程的抗震设防标准决策问题,澄清了最低抗震设防标准和大型桥梁工程抗震设防标准的关系,并基于多级设防的抗震设计思想,探讨了强调设防水准与结构性能要求、验算指标相对应的大型桥梁工程的抗震设防标准。In the seismic design of a bridge, the earthquake resistance level, which will be discussed in this paper, must be determined at the first. The lowest earthquake resistance level of bridge,; and the specific earthquake resistance level of a large bridge are clarified, and based on the muhilevel seismic design principle, the determination of the earthquake resistance level of large bridges is discussed, including the earthquake level, its corresponding structural performance and check target.
