摘　　要：从弹性力学的空间轴对称问题出发,从理论上推导建立了碳纤维布加固混凝土圆柱的应力计算公式,提出了碳纤维布加固混凝土圆柱后的等效轴压比概念,并给出了理论计算公式,从量上分析了环向粘贴碳纤维布加固混凝土圆柱的加固效果。最后结合工程实例指出了研究环向粘贴碳纤维布的预应力加固施工工艺的必要性。Based on the elasticity theory of spatial axial symmetry question, the paper established the stress formula for the carbon fiber clothes strengthening concrete circular section column theoretically. Also it proposed the concept of equivalent ratio of axial compressive force to axial compressive ultimate capacity of section on carbon fiber cloth strengthening concrete columns. The author produced the theoretical calculation formula for that. The effects of strengthening to glue the carbon fiber clothes on concrete circular section columns were quantitatively analyzed. By analyzing a project case, the article pointed out that it was necessary to research the strengthening craft of gluing the carbon fiber clothes construction with pre-stressed.
