摘　　要：介绍了在钢筋混凝土梁下部或梁截面高度范围内的集中荷载作用下,提高斜截面承载力的加固方法。应用该方法,不但提高了梁的斜截面承载力,同时也较大程度地提高了梁的受弯承载力和刚度,在实际工程中收到了良好的效果。A reinforced method to enhance the shear bearing capacity when the reinforced concrete beams are subjected to the concentrated load on the bottom or in the section height of the beam is introduced. The method enhances not only the shear bearing capacity, but also the bending resistant capacity and the rigidity of the beam. It has very good effect applied in the engineering practice and can be reference in the engineering based on the project situation.

关 键 词：集中荷载 拉脱效应 承载力 加固方法
