摘　　要：在工程加固中,新旧材料粘结面是结构的受力薄弱部位,针对以上问题,该文研究了水泥基灌浆料与混凝土粘结面的抗剪性能,试验设置了5个分组,每个分组制作3个试件,粘结面的处理方式是在一定的开槽基础上进行植筋,其中植筋率有所不同,通过实验数据对比分析不同植筋率对界面抗剪能力的影响。实验结果表明,随着植筋率的提高,界面抗剪能力不断提高。In engineering reinforcement,the bonding surface between the new and old materials is the weak stress part of the structure.In view of this problem,this paper studied the shear performance of the bonding surface between cement-based grouting material and concrete.In the test five groups were set up,each making three specimens.The bonding surface is treated by planting the reinforcement on a certain slotted basis,with different planting rates,and the influence of different reinforcement ratios on the shear capacity of the interface was compared and analyzed by experimental data.The experimental results showed that with the increase of the planting rate,the shear capacity of the interface is continuously improved.
