摘　　要：指出对剥离块体进行有限元分析,准确计算纤维复合材料(FRP)加固钢筋混凝土(RC)梁跨中保护层剥离应力的困难,提出解决这一困难的新思路,说明按新思路计算得到的剥离应力更加接近实际情况.In allusion to the difficulties to calculate the peeling-off stress accurately in concrete cover of midspan of FRP strengthening RC beams through analyzing the potential peeling-off-concrete-block with finite element analyses （FEA） , this paper puts forward a new thinking to solve the difficulties, and illuminates that the calculated peeling stress by new method approaches the real case better.
