为了给玄武岩纤维布（BFRP布）加固梁提供试验和理论数据，文中对前人理论试验成果的整理，推导了不同破坏形式下玄武岩纤维布加固梁抗弯承载能力计算公式并进行了理论与试验结果的对比；分析了BFRP布在加固方面相对于CFRP布的优势；根据抗弯性能试验，分析了纤维布加固量、应力历史对加固效果的影响。

英文摘要：

In order to provide experimental and theoretical data to beams strengthened with BFRP, the paper takes several researches based on previous theory and test results, including： deduce formulas about bending capacity of beams strengthened with BFRP under different collapse mode and compare it with the experimental results; theoretically analyses the advantage of BFRP on reinforcement over CFRP; according to the flexural performance test, analyses the influence on reinforcement effect by dosage on reinforcing and stress history of BFRPo
