摘　　要：夯土墙结构建筑因受其材料特性限制,故而在长时间下难以满足抗震要求。为进一步提高建筑荷载能力和抗震害能力,研究提出借助纤维水泥基复合材料辅之钢网的加固方案,对其变形情况、荷载能力等进行分析。结果表明,加固处理下的夯土墙体层间位移改善效果明显,其在2种地震波下的最大值为0.0024和0.0031,远小于夯土墙的0.0079和0.0072。且加固后模型较未加固的开裂和峰值荷载提高率均超过50%,墙体承载能力和抗变形性均有不同程度的提升。复合材料设计下的加固方案能有效减轻夯土墙房屋的破坏,改善其抗震性能,该材料能为生土结构房屋的实地加固提供参考思路。Due to the limitations of its material properties,rammed earth wall structures are difficult to meet seismic requirements over a long period of time.In order to further improve the load capacity and seismic resistance of buildings,a reinforcement scheme using fiber-reinforced cement-based composite materials supplemented with steel mesh is proposed,and its deformation and load capacity are analyzed.The results show that the interlayer displacement improvement effect of the rammed earth wall under reinforcement treatment is significant,with the maximum values of 0.0024 and 0.0031 under two types of seismic waves,which are much smaller than the 0.0079 and 0.0072 of the rammed earth wall.The cracking and peak load increase rate of the reinforced model exceeds 50%compared to the unreinforced model,and the bearing capacity and deformation resistance of the wall have been improved to varying degrees.The reinforcement scheme under the design of composite materials can effectively reduce the damage of rammed earth wall houses and improve their seismic performance,this material can provide reference ideas for the on-site reinforcement of raw soil structure houses.
