油气管道可接受风险标准值的界定研究

根据油气管道可接受风险评估的最低合理可行（ALARP）原则，结合社会风险ALARP原则（FN 准则）描述了风险可容忍线和可忽略线的确定方法；采用类别划区法界定了可接受性风险概率标准值；利用ALARP效用函数理论界定了可接受风险评价指标标准分值。既解决了我国资料缺乏情况下风险概率标准值的界定问题，又解决了当前评价模型中的可接受性风险标准在实践中如何体现的难题，对提高油气管道风险评估的质量有着重要的意义。

Defining Acceptable Risk Standard Values of Oil and Gas Pipeline

In this paper, the ALARP principle for acceptable risk assessment of oil and gas pipeline and the method of defining tolerance limit and neglectable limit of risk are described through combining the FN criteria, the acceptable risk probability standard values by adopting category zoning and acceptable risk assessment index standard scores are defined by using ALARP utility function theory. The former solves definition of risk probability standard value in the absence of information in our country, the latter answers how the acceptable risk standards of the current evaluation model functions in practice, which is of great significance for improving oil and gas pipeline risk assessment of the quality.
