摘　　要：通过试验的方法,对表层嵌贴CFRP(碳纤维增强塑料)板条后钢筋混凝土梁的抗剪性能进行了研究,并与未加固的构件进行了对比,试验研究表明,采用表层嵌贴法加固可以有效提高钢筋混凝土梁的抗剪承载力及刚度,抑制斜裂缝的产生和发展,减小裂缝宽度,提高混凝土梁的变形能力,改善其受力性能。Through experimental method, the shear performance of concrete beam after surface onlay Carbon Fiber Reinforced Plastic （CFRP） batten was studied and compared with tmreinforced structure. The experimental study indicated that NSM can enhance shear bearing capacity and rigidity of reinforced concrete beam effectively, inhibited crack occurrence and development, decrease crack width, enhance beam deformation capability and improve its mechanical performances.
