摘　　要：通过对八组72个试件两端开口式新型保温承重砌块砌体抗剪试验研究,分析了新型保温承重砌块砌体受剪破坏特征,考察了薄层砂浆和销键对该砌块抗剪强度的影响;研究了外墙砌块的外保温层部分对试件抗剪性能的影响,在此基础上,探讨了内、外墙新型保温承重混凝土砌块砌体的抗剪强度计算公式,根据现行砌体规范提出了建议计算方法,为其在实际工程中的应用及规程的编写提供基本理论和试验依据。The experimental study of shear strength was carried out by 8 groups （ 72 shear specimens ） of open-ended new type compound insulation concrete block masonry. The shear failure characteristics of a new type of thermal insulation bearing block masonry was analyzed, the influence of thin layer mortar and pin on the shear strength of the block was investigated, the influence of external thermal insulation layer of exterior wall block on shear performance of specimens was studied. The shear strength calculation formula of new type thermal insulation load-bearing concrete block masonry of internal and external wall was proposed, and the calculation method according to the existing masonry standard was put forward, which provides the basic theory and experimental basis for its application in practical engineering and the compilation of rules.
