摘   要：采用CFRP板对钢筋混凝土少筋梁进行了嵌入式加固，开展了不同加固方式试验梁的抗弯性能实验，分析加固长度、加固层数对加固效果的影响。实验得到了试验梁的荷载-挠度曲线、跨中钢筋荷载-应变曲线以及CFRP板的荷载变形关系，并对试件的破坏形态进行了分析。实验结果表明，嵌入式加固可以很好地提高试件的抗弯承载能力、改变试件的破坏形态，并随着加固材料长度和加固量的增加，加固效果更好。

Abstract: The reinforced concrete beam embedded with CFRP plate at the lower surface of the beams are designed, and the experiment of the flexural behavior are carried out with different embedded way, and the effect of the reinforced material length and the reinforcement layer on the reinforced impact is analyzed. The load-deflection curves of the specimen, the load-strain curves of cross bar and the load-deformation relationship of CFRP are measured, and the failure modes of the specimens are analyzed. The results show that the embedded reinforcement can improve the bending bearing capacity, change the failure mode of the specimen, and the reinforcement effect can be improved as the length of the CFRP plate and the reinforcement volume increasing.
