摘　　要：根据实际调查张家口地区村镇主要存在的建筑结构,并基于有限元分析软件ANSYS对土窑结构进行分析,建立两种类型的有限元模型;运用地震动加速度时程分析方法对两种模拟结构进行抗震分析,研究关键点位移和加速度的规律特点,结果显示:靠山模型在抗震性能方面极为不利,比独立模型更容易出现较大破坏,且两种结构产生共振后破坏明显变大;最后,提出土坯结构的震害响应机理并对两种结构的薄弱环节提出加固方案。Based on the finite element analysis software ANSYS, two types of finite element models are established according to the actual investigation of the kiln structure in Zhangjiakou area. The seismic analysis of the structure is carried out by using the time-history analysis method. The key points of displacement, acceleration and other relevant laws and characteristics are studied. The results show that the seismic performance of the backer model is more prone to damage than that of the isolated model, and the damage of the two structures becomes larger after resonance.Finally, the earthquake damage response mechanism of adobe structure and corresponding strengthening measures are proposed for the weak links of the two structures.
