摘　　要：为了有效提升油气管道的安全性,实现安全与成本的最优化,在生活质量指数(LQI,Life Quality Index)方法的基础上,针对油气管道建立了LQI评估模型;并以降低失效率为风险控制决策目标,根据我国油气管道行业的实际情况,提出了可接受的最小管道尺寸作为决策的标准。结果表明:LQI方法在与生命安全相关的风险控制决策上是有效的;通过LQI方法可以确定相关管道设计参数的可接受标准。In order to improve the safety of oil and gas pipelines and optimize the safety investment, an evaluation model for pipelines was established based on Life Quality Index （LQI）. Then, according to the condition of our country, the decrease of failure rate was set as the target for risk control decision-making, and the minimum acceptable diameter and wall-thickness was identified as the criterion for decision-making. The results showed that LQI method was effective in life-related risk decision-making process, and the acceptable design parameter of pipelines can be defined by this means.
