应用理论计算公式，对影响抗弯承载力的CFRP片材厚度、弹性模量以及混凝土强度等参数进行了分析，结果表明，使用弹性模量高、厚度大的CFRP片材加固的组合梁，承载力提高更大；采用高混凝土强度的梁，其极限抗弯承载力提高效果更明显。

Equations were used to oresent an analytical oarametric study on the flexural caoacity of the steel-concrete comoosite beam that has been strengthened with CFRP sheets. The imoortant oarameters included were the thickness of the CFRP sheets,the modulus of elasticity of the CFRP sheets,the concrete comoressive strength. The results show that strengthening using CFRP is more efficient for comoosite beams with high-er modulus,thicker CFRP sheets and higher concrete comoressive strength.
