摘　　要：提出适用于生土结构房屋承重夯土墙体新的施工方法,对采用不同方法夯筑的承重夯土墙体的受力及抗震性能进行试验研究,设计了3个墙体试件,分别采用传统水平分层夯筑、错层夯筑和加销键夯筑。对试件施加竖向荷载和低周反复水平荷载,研究采用不同夯筑方法建造的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;对比分析不同夯筑方法对夯土墙体水平受力性能和变形性能的影响。研究结果表明,与传统夯筑方法相比,错层夯筑法使墙体的承载和变形能力都得到提高;加销键夯筑使墙体的变形能力得到提高。New construction methods were put forward to apply to rammed earth walls of raw-soil structure.Three specimens were built by the way of traditional horizontal layer,alternate layer and add-pin-key construction methods,the mechanical behavior and seismic behavior of which were studied.Vertical loading and low cycle reversed horizontal loading were carried out on specimens to study the failure process,failure mode,hysteretic curve and skeleton curve feature.The horizontal bearing capacity and deformation capacity of the walls also were studied,the influence of different construction methods on which was analyzed.Test results indicate that,compared with the traditional construction method,the horizontal bearing capacity and deformation capacity of the wall can be improved by alternate layer construction method,and the deformation capacity of the wall can be improved by add-pin-key construction method.
