摘　　要：房屋倒塌是地震中财产损失和人员伤亡的主要原因。为开展北京韧性城市建设,摸清北京地区农村民居抗震性能底数,提升城乡防震减灾综合能力,抽样调查了北京市昌平区、怀柔区、延庆区、平谷区、朝阳区共7518栋农村民居。通过对农居结构类型、不同结构类型年代分布、抗震构造与结构布局、建筑材料与选址设计施工4个方面的分析,指出北京地区农居存在抗震设防不达标、选址和设计施工不规范、使用和维护管理不合理的抗震薄弱环节,并提出提高农村民居抗震性能的相关措施,如全面开展农居安全鉴定和加固工程,规范新建房屋、加强科学指导服务,提高农民的防震减灾意识。Building collapse is the main cause of property loss and casualties in earthquakes.In order to carry out the construction of a resilient city in Beijing,understand the seismic performance of rural residential buildings in Beijing area,and improve the comprehensive ability of urban and rural earthquake prevention and disaster reduction,a sampling survey was conducted on 7518 rural residential buildings in Changping District,Huairou District,Yanqing District,Pinggu District,and Chaoyang District of Beijing.Through analysis of four aspects of rural residential structure types,age distribution of different structural types,seismic construction and structural layout,building materials and site selection design and construction,it is pointed out that there are seismic weak links in rural residential areas in Beijing,including substandard seismic fortification,non⁃standard site selection and design construction,and unreasonable use and maintenance management.Relevant measures were proposed to improve the seismic performance of rural residential areas,such as comprehensively carrying out safety appraisal and reinforcement projects for rural residential buildings,standardizing new buildings,strengthening scientific guidance services,and enhancing farmers’awareness of earthquake prevention and disaster reduction.
