摘　　要：对村镇建筑中使用的生土结构房屋承重夯土墙的受力及抗震性能进行试验研究,设计了三片夯土墙试件.对试件施加竖向荷载和低周反复水平荷载,研究夯土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.通过对比试验,分析了构造柱、圈梁在夯土墙体中的作用以及土中掺和料对墙体受力性能的影响,指出影响夯土墙抗震性能的主要因素及一些施工中应该注意的问题,提出夯土墙承重墙体的抗剪承载力计算公式.The mechanical behavior and aseismic behavior of raw-soil structure with rammed earth wall, which is still used in our country, are studied. Three pieces of specimen on rammed earth wall are designed. Vertical loading and low cycle reversed horizontal loading are carried out on specimen aimed to study the failure process, failure mode, hysteretic curve and skeleton curve feature. The horizontal bearing capacity and deformation capacity of the wall also are studied. The actions of structural column and loop beam and the effect of admixture on the mechanical behavior of the rammed earth wall are analyzed by the contrast experiment. The influence factors of anti-seismic performance on such walls and the problems that requires attention in construction are pointed out. Formulas for calculating the shear bearing capacity of rammed earth wall are given.
