[提要] 在弹性理论的基础上，推导了任意线性分布荷载作用下混凝土梁粘贴加强片材加固时，片材端部剥离应力的计算公式。计算结果和有限元方法基本吻合。分析表明，剥离应力不但和混凝土梁的参数有关，还和粘胶层以及加强材料有关。

Based on the linear elastic theory, this paper presents a method for calculating the peeling stress at the sheetirIg end ofa RC beam witha strengthening sheeting under linear distributed loads. This method agrees well with the finite element method. The results show that the peeling stress is influenced not only by the parameters of the beam, but also by the adhesive and the strengthening material.
