［摘要］對(duì)未加固和用碳纖維布加固的石梁的抗彎性能進(jìn)行了試驗(yàn)研究，分析了未加固石梁與加固石梁在極限承載力和變形能力方面的差異。試驗(yàn)結(jié)果表明，碳纖維布加固石梁的承載力和變形能力皆有較大幅度的提高。對(duì)未加固石梁和碳纖維布加固石梁的抗彎承載力進(jìn)行了理論分析，提出了加固后石梁的抗彎承載力實(shí)用計(jì)算公式，公式計(jì)算結(jié)果與試驗(yàn)結(jié)果吻合較好，可用于指導(dǎo)實(shí)際工程的設(shè)計(jì)。

Abstract:The experimental study on the flexural behavior of the stony beams and stony beams strengthened by CFRP were carried out. The ultimate bearing capacity and deformation capacity were analyzed. The  results show that the flexural capacity and deformation capacity of the strengthened stony beams  are greatly improved. Based on the experimental results, the flexural capacity of the stony beams and CFRP strengthened stony beams were analyzed, and the formula of flexural capacity of strengthened stony beams was deduced. Compared with the tests results, the formula can be used to guide the design of practical engineering.
Keywords:CFRP; stony beam; strengthen; bearing capacity
