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。本文主要探讨了桥梁工程抗震设防水准与设防标准。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相对应的大型桥梁工程的抗震设防标准。 In the seismic design of bridge engineering, seismic fortification standard is the first problem to be solved. This paper mainly discusses the standards of seismic fortification and fortification of bridges. Clarified the relationship between the minimum seismic fortification standard and the seismic fortification standard for large bridge projects, and discussed the seismic fortification standards of large-scale bridge projects that emphasize fortification levels and structural performance requirements based on the seismic design idea of ​​multi-level fortifications.
