摘要

汶川地震中公路桥梁遭受重创,大量桥梁破坏甚至垮塌,难以修复.这些桥梁震害体现出山区桥梁震害的典型特征,为山区桥梁抗震设防提供了丰富的实例资料.在汶川地震现场桥梁震害调查资料的基础上,对汶川地震桥梁震害进行归纳、总结,提炼出该地震中桥梁震害的主要特征,为下一步继续深入探讨汶川地震桥梁震害形成机理和结构破坏过程,以及山区桥梁抗震设防对策与措施提供参考.
A lot of highway bridges were destroyed in the great Wenchuan earthquake,some of them co-llapsed.Damages of nine bridges were described,and main characteristics of the bridge damages occurred during the earthquake were summarized from investigation activity results after the earthquake.Many observations are preliminary.Some additional information is provided beyond other reports offered in the earthquake.
