摘要
为了解甘东南地区农村民居抗震性能现状,分析农村民居抗震薄弱环节,从而科学、合理地提高农村民居的抗震能力。结合当地调研资料数据,对甘东南地区农村民居进行现场调查,获取民居各类属性数据,划分甘东南民居主要结构类型及其分布特征与所占比例,针对不同类型的民居结构,对其进行抗震性能评价,分析其抗震薄弱环节及潜在危害。研究区现存五种典型房屋结构类型:土木结构、砖木结构、砖混结构、木架结构和窑洞,以前三种结构类型为主,其中有抗震构造措施的新建砖混结构和砖木结构抗震性能最佳,木架结构、老旧砖混结构和砖木结构次之,土木结构和窑洞抗震性能最差。研究结果对提高甘东南地区农村民居的抗震设防水平具有科学参考价值,也可为其他地区农村民居抗震性能的提升提供参考依据。
Actual seismic weak links of rural houses were analyzed to understand the seismic performance of rural houses in the southeastern region of Gansu Province to improve their seismic capacity scientifically and reasonably.Combined with local survey data,various attribute data of rural houses in the study area were obtained through field survey,and main structural types,distribution characteristics,and proportion of rural houses were divided.The seismic performances of different types of rural structures were evaluated,and their weak seismic links and potential hazards were also analyzed.Results show five typical types of building structures in the study area:civil structure,brick-wood structure,brick-concrete structure,wood frame structure,and cave;most of these structures are the first three types.Among them,the seismic performance of newly-built brick-concrete and brick-wood structures with seismic construction measures is the best,followed by a wood frame,old brick-concrete,and brick-wood structures.The seismic performance of civil structures and caves is the worst.The research results have scientific reference value for improving the seismic fortification level of rural houses in southeastern Gansu and other regions.
