摘　　要：指出纤维复合材料加固混凝土梁跨中剥离破坏的影响因素和破坏准则,讨论几种计算剥离应力方法的特点,提出更为简单可靠的直接对剥离块体进行有限元分析的新思路,并给出算例.The factors influencing peeling-off failure and failure criterion are summarized, and the characteristics of several methods for calculating the peeling-off stress are discussed. A new train of thought, which is more credible and simpler for analyzing the peehng-concrete-block with finite element method, is put forward. An calculating example is also provided.
