西藏米林MS6.9地震震害分析

Seismic hazard analysis of building structures for the Millin MS6.9 earthquake，Tibet

    摘要
  • 摘要: 2017年11月18日，西藏自治区林芝市米林县发生MS6.9地震。本文以2017年9月中下旬中国地震局地球物理研究所西藏野外考察建筑资料为基础，分析林芝周边4个考察点的房屋建筑抗震性能以及震后房屋建筑和震区道路的震害情况。重点分析鲁朗扎西岗村、易贡堰塞湖堤、米林镇帮加村、波密县岗堆镇岗堆村等4个考察点的房屋建筑情况以及震后破坏情况。这几个考察点分别位于地震烈度的Ⅶ度区和Ⅵ度区外。并给出震区房屋建筑在未来抗震设防的意见。

     

    Abstract: An earthquake（MS6.9）occurred in Millin county, Nyingchi city, Tibet Autonomous Region on November 18, 2017. Based on the building material in the Tibet fieldwork investigated by the Institute of Geophysics, China Earthquake Administration in September 2017, we analyzed the building construction and anti-seismic performance in the earthquake area before and after the Millin earthquake. We focused on the housing construction and the damage after the earthquake in Zhaxigang village in Lulang town, Yigong lake embankment, Bangjia village in Millin town, Gangdui village in Gangdui town. These sites are located at the seismic intensity of Ⅶ and Ⅵ area. This paper also gave some seismic fortification suggestions for future earthquakes.
