| Abstract: | 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. |
