摘要:
2022年9月5日12时52分，四川省甘孜州泸定县发生6.8级地震，文中以地震震后现场调查获得的7栋隔震建筑震害表现为依据，重点描述了调查所发现的隔震橡胶支座破坏、隔震配套黏滞阻尼器破坏以及隔震构造破坏等3类破坏现象。并以震中附近磨西镇中心烈度台获得的强震动记录特征分析为基础，对上述3类破坏现象产生的原因进行了分析讨论。进一步结合破坏原因分析结果，对目前我国建筑隔震技术发展亟待解决的技术问题给出了建议。
Abstract:
At 12:52 on September 5, 2022, an earthquake of magnitude Ms6.8 occurred in Luding County, Ganzi Prefecture, Sichuan Province. Based on the seismic performance of 7 base isolation buildings observed during the post-earthquake field investigation, this paper describes 3 typical seismic damage types, which are rubber bearing damage, viscous fluid damper damage and constructional measure damage. Characteristic analyses of the strong ground motions are conducted, which are recorded by the seismic intensity meter located at the center of Moxi town close to the epicenter. The causes of the 3 damage types are discussed. As well, with these analyses and discussion, the suggestions are provided to the urgent problems need to be solved in the development of base isolation for buildings in China.
