摘　　要：对复合混凝土-石膏墙板进行了聚苯板与石膏板之间、石膏板与混凝土之间连接面的抗剪性能试验,比较了3组9个试件的破坏过程、裂缝形态、荷载位移曲线、抗剪承载力和最大相对位移。试验结果表明,石膏板与混凝土之间和聚苯板与石膏板之间的粘接起决定性作用,连接面的抗剪承载力均远大于石膏板和聚苯板保温层自重及相应设计荷载要求。The shearing property tests of the link surface between the concrete and plasterboard as well as the link surface between the plasterboard and polyphenylene boaxxt are conducted with focus on composite concrete-plaster wallboard, and based on the shearing experiments of nine specimens, the failure progress, crack pattern, load-displacement curves, shear capacity and the maximum relative displacement are contrasted. The results indicate that the link surfaces between the concrete and plasterboard and between the plasterboard and polyphenylene board play the crucial roles in the shearing property. The shearing capacity of the link surface is far greater than the gravity of the plasterboard and polyphenylene board and the load requirement for the design.
