摘要

摘要: 北京时间2022年1月8日1时45分青海省海北藏族自治州门源县（37.77°N，101.26°E）发生6.9级地震，此次地震极震区为距震中4 km的兰新高铁硫磺沟大桥附近（Ⅸ度区，面积约157 km²）。调查结果显示，在极震区大西沟至硫磺沟区域，道路、桥梁及房屋破坏较严重。沿区域内长约22 km的托来山-冷龙岭断裂带附近，道路形成多处裂缝与挤压鼓包，桥梁整体倾斜移位，房屋不同程度破坏。对极震区兰新高铁硫磺沟大桥及周边道路、房屋进行实地调查与震害分析，提出灾后重建及震害防御意见：对于灾区房屋建筑，组织专业技术人员进行详细调查及安全鉴定；建议定期对房屋建筑进行隐患排查及加固；对于兰新高铁硫磺沟大桥，建议原地修建，加设减隔震装置、连梁及柔性限位装置。

Abstract: At 1:45 a.m. on Jan 8th, 2022, a magnitude 6.9 earthquake occurred in Menyuan County (37.77°N, 101.26°E), Haibei Tibetan Autonomous Prefecture, Qinghai Province. The epicenter of the earthquake is near the Liuhuanggou Bridge on the Lanxin high-speed railway, which is 4 km away from the epicenter (the area of earthquake intensity 9 is about 157 km²). The survey results show that roads, bridges and houses were seriously damaged from Daxigou to Liuhuanggou in the extreme disaster area. In the vicinity of the 22 km Long Tuolaishan-Lenglongling fault zone in the region, it can be seen that the damage type of several cracks and extrusion bulges were formed on the ground, the bridge tilted and shifted as a whole, and the house was damaged to varying degrees. The field investigations and earthquake disaster analysis were carried out on the Lanxin High-speed Railway Liuhuanggou Bridge and surrounding road and houses in the extreme disaster zone, and relevant suggestion on post-earthquake reconstruction and earthquake disaster prevention were put forward: Conducting detailed house safety appraisal by the professional personnel of housing construction organization in disaster area; Suggesting to conduct hidden danger investigation and reinforcement work on housing construction regularly; For the Liuhuanggou bridge, it is recommended to rebuild in situ with shock-absorbing and isolating devices, limiting and connecting beam device.
