摘　　要：在分析混杂纤维(HFRP)加固混凝土梁的破坏形态及界限破坏特点的基础上,开展混杂纤维加固混凝土梁的承载力的理论研究,并提出相应的近似计算公式。对照试验结果表明计算公式能够满足要求,对实际工程有一定的指导意义。On the basis of analyzing the destructive state and critical destructive characteristics of the concrete beam of hybrid fiber-reinforced plastics （HFRP）, the theoretical study of the bearing capacity of the HFRP concrete beam will be developed and the corresponding approximate formula will be put forward.The experimental results show that this formula could meet the requirements and thus have certain directive significance to the actual projects.
