摘　　要：为了研究钢筋与火山渣混凝土间的粘结性能,利用有限元软件ABAQUS对不同钢筋直径、不同粘结长度进行拉拔模拟,分析了火山渣混凝土不同钢筋直径和不同粘结长度下的极限粘结应力变化规律.结果表明,随着钢筋直径的增加钢筋和火山渣混凝土的粘结强度逐渐降低,随着粘结长度的增加钢筋和火山渣混凝土的粘结强度逐渐降低.In order to study the bonding performance between reinforcement and pozzolanic concrete,The finite element software ABAQUS is used to simulate the drawing of different reinforcement diameters and bond lengths,the variation law of ultimate bond stress of pozzolanic concrete under different reinforcement diameter and bond length is analyzed. The results show that the bond strength between reinforcement and pozzolanic concrete decreases with the increase of reinforcement diameter,and the bond strength between reinforcement and pozzolanic concrete decreases with the increase of bond length.
