摘要
本文对含缺陷压力管道裂纹穿透后的失效形式和失效分析方法进行了回顾，得出了确定临界裂纹长度的分析方法的选择图，并在三种载荷条件下，分别推导了含环向缺陷的压力管道临界裂纹长度的求取公式。
In this paper, failure forms and analysis methods of pressure piping with Circumferential defects are summarized, and a selection diagram of analysis methods for determination of critical crack length is given. Under three kinds of Loads,the formulas of calculating critical crack length are derived respectively, and some experimentl data is used to verify them.
