摘　　要：目的研究矿渣混凝土实心砖砌体沿通缝截面的抗剪强度计算指标．方法参照〈砌体基本土学性能试验方法〉（GBJ129）的要求，采用9块砖组成的双剪试件，对48个矿渣混凝土实心砖砌体试件进行了沿通缝截面的抗剪试验．结果矿渣混凝土实心砖砌体抗剪强度的计算指标超过烧结普通砖砌体抗剪强度的30％～50％，将试验结果进行回归分析，给出了矿渣混凝土实心砖砌体抗剪强度平均值的计算公式．结论矿渣混凝土实心砖砌体抗剪性能良好，其砌体抗剪强度计算指标可按〈砌体结构设计规范〉（GB50003）中烧结普通砖砌体抗剪强度计算指标取值．The paper studies the shear strength of the slag solid concrete brick masonry. The specimens were composed of 9 bricks, and the test of 48 slag solid concrete brick masonry specimens was carried out. The result indicates that the shear strength of the slag solid concrete brick masonry is higher than that of burned common brick masonry. A formula is proposed to calculate the average value of the shear strength of the slag solid concrete brick masonry through the regression method. The result shows that the shear strength of the slag solid concrete brick masonry is good, and the shear strength of the slag solid concrete brick masonry can be chosen from the value of burned common brick masonry in Code for Design of Masonry Structure.
