摘　　要：对通用的ASME法与有限元法进行分析比较,阐述了这两种方法计算结果之间的关系,以及ASME法公式的由来的一些认识,并对开孔边缘弯曲应力的分类问题进行探讨。For a long time, the methods of reinforcement calculation and assessment for large opening in pressure vessel have been controversial. In this article, the comparison of the method recommended in ASME code with finite element method was carried out. The relation of the results from these two methods was indicated, and the original source of the method in ASME was introduced. Finally, the classification of the bending stresses at opening boundary was discussed.
