摘　　要：对混杂纤维材料补强加固钢筋混凝土受弯构件的破坏形态和极限状态进行了试验研究,分析了加固梁与对比梁的刚度变化,得出了混杂纤维加固增高混凝土梁可以有效提高原梁的刚度等试验结论,为实际工程加固设计提供了有用的指导。The failure modes,ultimate flexural limit states of the flexural reinforced concrete members strengthened with hybrid fiber reinforced polymer（HFRP） were studied in this article.The stiffness change of the reinforced beams and the original beams was researched.Some conclusions such as the rigidity of raised concrete beam reinforced with hybrid textile fiber can be enhanced effectively were made.This was very helpful for the practical design.
