摘　　要：针对五根受损程度不同的混凝土梁,采用预应力与非预应力进行加固对比,试验分析预应力玻璃纤维布加固后的混凝土梁的正截面受力性能,研究不同加固方式以及不同的受损程度对混凝土梁的抗弯承载力影响。同时对预应力加固混凝土梁的正截面承载力进行理论分析和推导,建立了实用的理论计算公式。理论计算结果与试验数据符合良好。In this paper, five different levels of damage to the concrete beam, prestressed compared with non-prestressed reinforcement,testing of prestressed glass fiber reinforced polymer flexural after the performance of different strengthening methods on the concrete beam flexural bearing capacity. At the same time reinforced concrete beams prestressed flexural capacity of the theoretical analysis and derivation,the establishment of a practical calculation formula, the theoretical results with experimental data well
