喀什地区位于地震设防烈度较高的区域,其老旧建筑以生土为主,高设防烈度和未经抗震设计的结构形成鲜明对照。通过对实地采取土样进行材性试验,判定其基本力学特性,建立本构模型。在生土的特性研究基础上,采用有限单元方法对实测结构模型进行分析,并采用与实测结果对照的方法,确定结构抗震性能,最后对生土改性和生土建筑加固方法提出建议。 The Kashgar region is located in a region with high earthquake fortification intensity. The old buildings are dominated by raw soil, with high fortification intensity and a structure without earthquake resistance design in stark contrast. By taking a soil test on the ground to determine its basic mechanical properties and establish a constitutive model. Based on the study of soil properties, the finite element method is used to analyze the measured structural model, and the method of comparison with the measured results is used to determine the seismic performance of the structure. Finally, suggestions are made for the methods of soil modification and reinforcement of raw earth buildings.
