摘　　要：基于评价汶川地震重灾区、极重灾区公路桥梁抗震设防标准的需要,对震区桥梁建设所依据的3个版本抗震设计规范设防标准发展情况进行介绍和评价,并对国内外现行公路桥梁抗震设计规范的设防标准和设防目标进行比较研究,在此基础上评价我国公路工程抗震设计规范设防标准的发展和现状。Based on need of evaluation for seismic fortification criteria of highway bridges in the harder-hit and extremely harder-hit areas in Wenchuan Earthquake, this paper introduces and evaluates development of fortification criteria in 3 versions of seismic design codes for construction of bridges in the hit areas , compares and studies fortification criteria and targets in existing seismic design codes for highway bridges at home and abroad, and based on which evaluates development and status quo of fortification criteria in seismic design codes for China national highway project.
