摘　　要：应用等效体积单元(Representative Volume Element,简称RVE)方法,对6个土坯砌体试件抗压强度试验进行数值计算分析,并与试验结果进行对比,验证了RVE方法应用于土坯砌体的合理性。在此基础上,对不同配筋率的钢丝网水泥砂浆加固土坯砌体,采用二次RVE方法进行数值计算,并与土坯砌体进行对比,验证了钢丝网加固土坯砌体的有效性与二次RVE方法应用于加固土坯砌体数值计算的合理性。进而找出加固砌体的最优配筋率,为村镇传统生土建筑的改造与加固设计提供参考依据。In this paper,the author has made compressive strength test on the six adobe masonry and then performed the numerical simulation using the method of representative volume element（RVE）.By comparing the two results,it verifies the reasonability of RVE applied in adobe masonry.On this basis,it adopts the way of second RVE to apply to the numerical simulation in different percentage of reinforcement of adobe masonry strengthened with ferrocement mortar.By comparing with the result of adobe masonry,it verifies the effectiveness of adobe masonry strengthened with ferrocement mortar and the reasonability of second RVE applied in reinforced adobe masonry.And then it finds out the optimal reinforcement ratio of reinforced masonry.The results of the research can be used as the reference for the rebuilding reinforcement of traditional abode buildings in rural areas.
