- Abstract:为研究聚合物水泥砂浆(polymer coment mortar,PCM)-碳纤维增强复合(carbon fiber reinforced polymer,CFRP)网格加固层与混凝土界面的黏结滑移关系和应力传递机理,对18个试件进行了拉拔试验,观测了其破坏形态和荷载-滑移关系,分析了CFRP网格的结点数、网格间距和不同类型的PCM对界面的黏结滑移和应力传递的影响。试验结果表明:低弹性PCM变形能力虽优于高强度PCM,但其在受拉过程中由于变形,易产生较大的应力,从而导致混凝土与PCM之间过早产生剥离破坏;CFRP网格在抗拉中起到约束滑移的作用,并随着网格间距的增加,横向网格筋的约束作用越显著;纵向网格筋的应变均呈现出从加载端到自由端逐渐减小的趋势,拉应力通过CFRP网格的结点依次传递给PCM和混凝土,其中第1网格结点的抗拉效果最明显;为使CFRP网格与PCM、混凝土有足够的黏结强度,即网格结点的应变分担率总和达到90%以上,则网格结点至少要3个及以上,且网格结点应随着网格间距的减小而增多。
