我国的《公路工程抗震设计规范》采用以强度破坏为目标准则的单一水准抗震设计方法,难以真正实现抗震设计中的“小震不坏,中震可修,大震不倒”的分级设防标准。而日本2001年版的《道路桥示方书·同解说V耐震性能篇》(下文简称为“日本桥规”)中,明确划分了桥梁抗震设计的性能目标、概念设计及其指标,对不同发生概率的设计地震水准直 China’s “Code for Aseismic Design of Highway Engineering” adopts the single-level seismic design method with the goal of strength destruction as the criterion, and it is difficult to truly realize the standard of fortification and fortification of “small earthquake is not bad, moderate earthquake can be repaired and large earthquake does not fall” . However, in Japan’s 2001 edition of “Road and Bridge Diagrams and V-Earthquake Resistance Capabilities” (hereinafter referred to as “Japan Bridge Rules”), the performance objectives, conceptual design and indicators of seismic design of bridges are clearly divided. Different probability of occurrence The design of earthquake water collimation
