摘　　要：以某水电站排架T形梁补强加固为例,介绍了采用碳纤维布半包裹梁腹板的加固方法,以控制T形梁裂缝的开展并提高其承载能力,分析了T形梁加固后的受力状况,给出了加固后的承载力计算公式。计算结果表明该方法能使T形梁承载能力提高60%以上,为有效解决同类实际工程问题提供了一种新的方法。Strengthening T beam frame fiber reinfored polymer strip wrapped along the rib of beam can restrict crack development and increase bearing capacity.The behaviors of strengthened beams and CFRP strips are analyzed,and the formulas of bending capacity for strengened beam are presented.The calculation results show that the bending capacity of beams increases by sixty percent and serves as a scientific way to solve the practical problem of the project.
