摘　　要：砼砌块砌体中材料强度匹配问题是工程设计中需要解决的问题.综述了国内外学者对砌体受压性能的研究成果,分析并总结了影响砌体抗压强度的主要因素.依据芯柱和砌块竖向变形协调原理,推导得到了灌孔砼砌块砌体中灌孔砼强度与砌块强度之间的关系表达式,据此编制了灌孔砼砌块砌体材料强度的最佳组合表,可指导工程设计.该研究成果丰富了砌体结构的基本理论,为规范条款提供了理论依据,同时对灌孔砼砌块砌体在工程中的应用具有参考价值.The material strength match of grouted concrete block masonry must be solved in engineering design. The research results of the compressive behavior of masonry at home and abroad were summed up. The main factors influencing the compressive strength of masonry were analyzed and summarized. The relation between grouted prism strength versus grout strength was derived according to their vertical deformational coordinative principle. The optimum combination table of the material strength of grouted concrete block masonry was compiled,which can be used in engineering design. This research result has enriched the fundamental theory of masonry structure and provided theoretical evidences for code items. At the same time, this method can be used for references when grouted concrete block masonry is used in engineering.
