摘　　要：通过含水率对砖砌体抗剪强度影响规律的试验,分别测出不同砖砌体试件整体含水率、砖的含水率和砂浆缝砂浆的含水率与抗剪强度之间的关系,得到砖砌体试件随浸泡时间含水率的变化规律,给出了考虑含水率的砖砌体抗剪强度计算公式.通过试验可以看出,含水率对砖砌体抗剪强度有着重要影响,有关规范中应予以考虑.Series of experiments were carried out to research water content＇s effects on shearing strength of the brick masonry.The relationship between soaking time and shear strength of brick masonry specimen was measured,and tendency changing with soaking time of overall moisture content,moisture content of brick and mortar joint was obtained.A regressive formula of shearing strength of brick masonry,which can take account of effects of water content,is suggested.The results show that,1） the water content plays an important role in the shearing strength of brick masonry;2） enough attention should be paid to the design specification.

关 键 词：砖砌体 含水率 抗剪强度 回归分析
