摘要
2023年12月18日甘肃省临夏回族自治州积石山县发生6.2级地震,给青海省海东市民和回族土族自治县、循化撒拉族自治县、化隆回族自治县和黄南藏族自治州同仁市部分地区造成重大人员伤亡和财产损失.对此次地震采用现场考察、归纳总结的方法进行了震害特点分析,结果表明:灾区土木结构、砖木结构、砖混结构、钢混结构类型的房屋都受到了相当程度的损坏,农村居民住宅用房破坏严重.倒塌房屋以土木、砖木结构的老旧农房为主;严重损坏房屋以砖木、砖混结构的农房、城镇居民用房为主;一般损坏房屋以钢混、砖混结构的非住宅用房为主.地震烈度与地质灾害隐患点的分布有一定的关联性,烈度越高的地区,地质灾害隐患点越多.
Abstract
On December 18,2023,a 6.2-magnitude earthquake struck Jishishan County,Linxia Prefecture,Gansu province.The earthquake caused heavy casualties and property losses to Minhe County,Xunhua Coun-ty,Hualong County and Tongren City of Huangnan Prefecture in Qinghai Province.In this paper,the charac-teristics of the earthquake damage are discussed by field investigation and summary.The results show that the buildings of civil structure,brick-wood structure,brick-concrete structure and steel-concrete structure have been damaged to a considerable extent,and the residential buildings of rural residents have been serious-ly damaged.The collapsed houses are mainly old farm houses of civil,brick and wood structure.The severely damaged houses are mainly agricultural houses of brick and wood,brick and concrete structure,and urban residents houses.Generally,the ruined houses are mainly non-residential houses with steel and brick struc-tures.There is a definite correlation between seismic intensity and the distribution of geological hazards.The higher the intensity,the more geological hazards.
