［摘要］针对天津地区3个区县农居，提出了农居抗震性能三级调查方法，并阐述了应用三级调查方法的基本原则，根据天津农村地区抗震设防要求，给出了3个区县的地震动设防参数。根据调查的两万多栋农居，分析了农居抗震现状，根据农居承重墙体砂浆强度和抗震构造措施不同分析了农居构造特征的时空分布，分析了土坯、石木、砖木和砖混四种结构类型的抗震现状。可为现有农村地震安全提供技术支持和科学依据。

Abstract:A three-level seismic performance investigation method for rural residences was put forward to apply in the rural residences in three districts and counties in Tianjin area, and the basic principle of applying the three-level investigation method was expounded. According to the requirements of seismic fortification in rural areas of Tianjin, the seismic fortification parameters of three districts and counties were given. According to the survey of more than 20 000 rural residences, the seismic status of rural residences was analyzed. According to the strength of mortar and seismic structural measures of load-bearing walls of rural residences, the spatial and temporal distribution of structural characteristics of rural residences was analyzed. The seismic statuses of adobe, stone, brick-wood and brick-concrete structures were analyzed to provide technical support and scientific basis for seismic safety of existing rural residential structures.

Keywords:rural residential structure; seismic investigation; seismic performance; seismic status
