【摘要】：汶川地震积累了大量公路桥梁的震害资料,这为开展公路桥梁震害与地震烈度的相关性研究奠定了基础。本文整体介绍了汶川地震公路桥梁的震害情况,通过统计整理近2 000座桥梁的震害资料,分别得到了拱桥与梁桥的主要震害类型,并探讨了它们的发生概率与不同地震烈度的对应关系,还分析了关键构件的破坏程度随地震烈度的变化规律。最后,基于桥梁破坏等级和典型震害的形式分别提出了评定地震烈度的建议指标,并进行了对比分析。
[Abstract]:Seismic data of the Wenchuan earthquake has accumulated a large number of highway bridges, which laid the foundation for developing seismic damage and seismic intensity correlation of highway bridges. This paper introduces the overall damage in the Wenchuan earthquake of highway bridges, through the statistics of nearly 2000 bridge seismic data were obtained by the main earthquake damage arch bridge and bridge type, corresponding the relationship between them and the probability of different earthquake intensity is discussed, also analyzed the damage degree of key components varies with the intensity of earthquake. Finally, the bridge damage level and typical damage forms put forward suggestions based on the evaluation of earthquake intensity index, and a comparative analysis.
