【摘要】：汶川地震積累了大量公路橋梁的震害資料,這為開展公路橋梁震害與地震烈度的相關(guān)性研究奠定了基礎。本文整體介紹了汶川地震公路橋梁的震害情況,通過統(tǒng)計整理近2 000座橋梁的震害資料,分別得到了拱橋與梁橋的主要震害類型,并探討了它們的發(fā)生概率與不同地震烈度的對應關(guān)系,還分析了關(guān)鍵構(gòu)件的破壞程度隨地震烈度的變化規(guī)律。最后,基于橋梁破壞等級和典型震害的形式分別提出了評定地震烈度的建議指標,并進行了對比分析。
[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.
