| 摘 要： | 应用模糊随机概率理论，在同时考虑压力管道评定参数的随机性和失效模式模糊性的基础上，指出含缺陷压力管道的失效概率实际上是一个模糊随机概率，进而提出了计算含缺陷压力管道模糊失效概率的方法。这种方法与仅考虑参数的随机性相比，更科学合理、更符合工程实际。

| Abstract: | Based on the theory of fuzzy probability, the randomness of assessment parameters and fuzziness of failure modes of pressure piping are both considered,it is pointed out that the failure probability of pressure piping is a fuzzy failure probability in fact, and a method to compute the fuzzy failure probability of pressure piping is proposed. Compared with traditional reliability analysis method, this method is more reasonable. |
