摘　　要：对CFRP板嵌入式加固钢筋混凝土梁进行静力受弯试验研究,分析板条宽度,配筋率,嵌贴长度对开裂荷载,屈服荷载,极限荷载,曲率延性以及构件刚度的影响。试验结果表明:在保证足够CFRP板嵌贴长度条件下,随着加固量的增加,梁的抗弯承载力和刚度明显提高;加固梁与对比梁相比,曲率延性降低。The test group experimented on the RC beams strengthened with near-surface mounted CFRP plate under static bends load.It analysis slat width, reinforcement ratio, mounted length of cracking load, yield impact load, ultimate load, curvature ductility and member stiffness.The results show that under the condition of ensure enough embedded paste CFRP plate length, flexural capacity and stiffness of the beam significantly improved with the increase of the amount of reinforcement, reinforcing beam compared to the control beam, curva- ture ductility decreases.
