摘　　要：以张家口地区市抗震设防要求相对较高的宣化区为对象,对宣化区14个乡镇的住宅民居抗震现状进行有针对性的调查,重点调查农村民居的结构特点、抗震性能等。利用综合分析方法,建立研究区农村民居抗震性能模型,并对每一个评价单元进行定量分析,通过抗震性能参数值的计算,发现研究区农村民居抗震性能普遍较差,在此基础上本文提出防震减灾的措施和对策,为提升农村民居的抗震能力提供参考。Xuanhua district,which has relatively high seismic fortification requirements in Zhangjiakou area,is selected as investigation target.The earthquake resistance status of residential houses in 14 villages and towns in Xuanhua district was investigated,focusing on the structural characteristics and seismic performance of rural houses.Using a comprehensive analysis method,a model of the seismic performance of rural houses in the area was established.Quantitative analysis was performed on each evaluation unit,and the calculation of seismic performance parameter values was completed.It is found that rural houses in this area generally have poor seismic performance.The measures and countermeasures for earthquake prevention and disaster reduction are proposed,which provide reference for improving the earthquake resistance of rural buildings.
