摘　　要：为改善被加固混凝土梁的抗剪性能,提出在梁底粘贴预应力碳纤维布和在梁端部两侧粘贴碳纤维布复合加固技术。本文设计了五根无腹筋混凝土梁,进行静力加载试验,试验分析预应力碳纤布加固后的斜截面受力性能,研究不同加固方式对混凝土梁的抗剪承载力影响,提出了具有一定工程实用价值的技术结论与建议。In order to improve the shear capacity of concrete beam,a new composite reinforcement technique that pasting CFRP on both side of the end of the concrete beam and prestressed CFRP at the bottom was used. This paper designed five concrete beams without web reinforcement to carry out static loading experiment and analyzed oblique cross-section mechanical properties of the beams which reinforced by prestressed CFRP through experiment, researched the impact of concrete beams on the shear strength in different reinforcement and made a technical conclusions and recommendations which had a certain practical value.
