摘　　要：为了提升燃气聚乙烯管道法定检验的有效性,本文通过案例调研分析、风险因素识别、风险评价技术比对等方法,基于风险矩阵分析法并结合城镇燃气聚乙烯管道服役与检验现状,构建了适用于国情的城镇燃气聚乙烯管道风险评价体系。经现场验证:该评价体系能真实有效地反映城镇燃气聚乙烯管道的风险水平,为开展城镇燃气聚乙烯管道的法定检验、推进城镇燃气安全排查专项整治工作提供有力的技术支撑。In order to improve the effectiveness of the statutory inspection for urban gas polyethylene pipelines,a risk evaluation system suitable for urban gas polyethylene pipelines in China was established based on risk matrix analysis method and combining the actual situation of operation with inspection for the pipelines through case investigation and analysis,risk factor identification,risk assessment technology comparison,etc..The application shows that the evaluation system can effectively reflect the true risk level of urban gas polyethylene pipelines,and provide some powerful technical support for carrying out legal inspection and promoting the special safety improvement project of urban gas polyethylene pipelines.
