摘　　要：借助材料力学、弹性力学以及高等数学的相关理论,对碳纤维布加固有初始裂缝混凝土梁在对称集中荷载作用下的界面剪应力进行了公式推导,并结合一算例与有限元分析结果进行对比。This paper has presented the whole process for the formula of the interface shearing stress in virtue of mathematics and mechanics of elasticity as well as material strength. The theoretic result is discussed and compared with that of finite element analysis and some significant conclusions have been acquired.
