摘　　要：根据纤维复合材料加固钢筋混凝土桥梁的作用原理,结合规范及相关试验结果,导出了芳玻韧布加固预应力混凝土空腹矮T梁的承载力计算公式及其施工工艺。结合工程实例进行加固后截面承载力计算,结果验证了芳玻韧布用于桥梁加固中的有效性。Based on the mechanism of reinforced concrete bridge strengthened with composite fibre materials and combining with the cede and related experimental results, the canting capacity formulas and construction technologies of prestressed concrete hollow and short T-section beam strengthened with GFRP and AFRP composite fabric are suggested. Combining with the project example, calculated results of the capacity of strengthened section show the validity of GFRP and AFRP composite fabric applied in bridge strengthening.
