摘　　要：对村镇建筑中使用的生土结构房屋承重土坯墙体的受力及抗震性能进行试验研究,设计了一片土坯墙试件。对试件施加竖向荷载和低周反复水平荷载,研究土坯墙体在地震荷载作用下的破坏过程、破坏形态、滞回曲线和骨架曲线的特征以及墙体的水平承载力和变形能力等。分析影响土坯墙抗震性能的主要因素。研究表明土坯墙体的破坏模式与砖砌体相似,采取一定的抗震构造措施后,土坯墙体也具有较好的承载力和一定的变形能力,可以在设防烈度6度、7度的地区使用。The mechanical behavior and aseismic behavior of raw-soil structure with adobe wall,which was still used in our country,were studied.A piece of specimen on adobe wall was designed.Vertical loads and low cycle horizontal loads were loaded on specimen aiming to study the failure process,failure mode,hysteretic curve and skeleton curve feature.The horizontal bearing capacity and deformation capacity of the wall were also studied.The influence factors of anti-seismic performance on such wall were pointed.Test results indicate that the failure mode of adobe wall is similar to that of brick masonry wall.Furthermore,better bearing capacity and deformation capacity can be obtained by taking some proper aseismic details.Thus,this type of raw-soil structure housing with adobe wall is suggested to be applied in the 6 and 7 degrees fortification regions.
