摘　　要：详细介绍了汶川地震中典型桥梁的震害情况,探讨其破坏模式,并有针对性地提出了强震区桥梁的抗震对策,为类似强震区新建桥梁设计及已建桥梁的补强加固提供一些参考。By introducing typical bridge damage samples in Wenchuan earthquake,the failure modes of bridges were discussed.Based on the failure modes,aseismatic measures were put forward,which were valuable for new bridges design and existing bridges reinforcements in similar regions of strong earthquake.
