摘　　要：提出一种内置绳网的生土结构房屋承重夯土墙体及其建造技术,对该种夯土墙与按照传统方法夯筑的承重夯土墙的受力及抗震性能进行试验研究,各设计了一片墙体试件.对试件施加竖向荷载和低周反复水平荷载,对比研究两种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.分析内部设置绳网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,与传统夯土墙相比,内置绳网夯土墙体的承载和变形能力更高,将该种夯土墙应用于生土结构房屋,可使房屋的整体性增强,抗震能力得到提高.A new design of rammed earth walls with built-in rope nets with its construction technology was proposed. Two specimens were built by way of the new construction technology and traditional construction technology, with the mechan- ical behavior and seismic behavior studied. Vertical loading and low cycle reversed horizontal loading were carried out on specimens aimed 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, with the influence of the built-in rope nets ana- lyzed. Test results indicated that compared with the traditional construction method, the horizontal hearing capacity and deformation capacity of the new design wall was improved by built in rope nets construction method. Thus, with the built-in rope nets rammed earth walls, the integrity of the raw-soil structure houses is strengthened, and the seismic be- havior improved.
