| description | The invention discloses a method for judging the risk of a buried polymer polyethylene pipeline for fuel gas. The method comprises the following steps: S1, collecting historical accident machine detection report data and summary of a buried polymer polyethylene pipeline for fuel gas; S2, establishing a risk database of the buried polymer polyethylene pipeline for fuel gas; S3, determining the failure risk grade division of the buried polymer polyethylene pipeline for fuel gas; S4, determining the failure risk judgment index of the buried polymer polyethylene pipeline for fuel gas. According to the characteristics of a polyethylene fuel gas pipeline and statistical data of domestic and overseas related urban fuel gas polyethylene pipeline system accident causes, based on the Kent scoring method and the analytic hierarchy process, extenics is introduced, four main risk judgment indexes including third-party damage, design factors, misoperation factors and intrinsic safety quality are planned to be designed, an |
