| 摘 要： | 整理并分析汉中地区的地震背景、地震动参数和地质灾害，调查区域内地震动参数有差异的9类样本行政镇的931栋典型农村房屋，研究典型农村房屋的结构类型、抗震概念设计和建造场地等因素对房屋抗震性能的影响。结果表明:汉中地区地质构造复杂，深大断裂发育，94.7%的区域为灾害易发区，存在4个地震烈度异常区；农村既有房屋结构类型有土木结构、砖木结构、砖混结构和框架结构，其中砖木结构和砖混结构是主要的抗震结构类型，框架结构是新型抗震结构类型；区域内农村房屋的建造场地条件危险性大并且抗震概念设计不足，房屋震害严重，村民的工程地质和地震地质等相关知识匮乏。该研究可为村镇房屋的防震减灾工作提供参考。

| Abstract: | Based on the earthquake background, ground motion parameters and earthquake hazards in Hanzhong regions as well as analysis to structure types, seismic concept design, and site types for 931 typical rural buildings located in nine towns with difference in ground motion parameters, the factors (structure types, seismic concept design, and site types) influencing the seismic resistance behavior of typical rural buildings in Hanzhong has been studied. The results indicate that geological structure is complex in Hanzhong with deep and large faults. In the tested sites, 94.7% sites are vulnerable to geological hazards with four identified regions of anomalous seismic intensity. The main types of rural buildings are soil-wood structure, brick-wood structure, brick-concrete structure and frame structure. Brick-wood structure and brick-concrete structure are among the main types in seismic resistance, while the frame structure is the emerging type. Incorrect selection in construction site, lack of awareness in seismic concept design, and ignorance in understanding on geological knowledge on earthquake-resistance of local rural people are the main reasons leading to severe damages triggered by earthquake. This paper can be as a reference for the seismic resistance of rural buildings. |
