本文分析了相关行业概率安全评定失效准则和压力容器失效事故统计结果 ,分析认为目前压力容器概率安全评定使用的失效准则主要来源于压力容器失效事故的统计结果。作者从常规设计的角度探讨了压力容器的失效概率问题。

In this paper, the probabilistic failure criteria for the safety assessment of the pressure vessels were presented. Based on the relevant criteria, it is concluded that the different criteria should be appointed to the vessels with different importance. The failure probability is calculated on the basis of the regular design procedure. Then, in accordance with the classification rules of the pressure vessel, three probabilistic failure criteria were recommended.
