摘　　要：为研究矩形孔烧结页岩砖砌体抗压强度和弹性模量,以砂浆强度为试验主要参数,对9个矩形孔烧结页岩砖砌体试件和9个烧结粘土砖砌体试件进行抗压强度试验,总计18个试件,进行抗压强度试验,由试验结果分析砌体试件破坏的3个阶段以及试件应力-应变关系。试验结果表明,现行砌体规范中的砌体抗压强度平均值计算公式fm=k1fα1(1+0.07 f2)k2适用于矩形孔烧结页岩砖砌体,且安全储备较大,矩形孔烧结页岩砖砌体弹性模量也完全符合现行规范要求。In order to study the compressive strength and elastic modulus of burnt shale brick masonry with rectangular hole,mortar strength was chosen as the main parameter,and 9 burnt shale and clay brick masonry specimens with rectangular hole were made.Compressive strength tests were carried out on the 18 brick masonry specimens.The 3 damage stages and stress-strain relationship of the specimens were analyzed by the tests,The results show that the present formula for the calculation of average masonry compression strength according to the code,fm= k1fα1（1 ＋ 0.07 f2） k2,is applicable to the burnt shale brick masonry with rectangular hole,and it has enough safety reservation; that,the elastic modulus of the masonry also meets the requirement of current specification.
