In order to ensure the safe and stable operation of urban gas pipeline system,this paper mainly aims at the safety problems of urban gas pipeline due to damage,corrosion,facility failure and human factors,establishes a set of relatively general urban gas pipeline risk assessment system,and determines the weights of related factors by AHP,and makes qualitative and quantitative analysis of urban gas pipeline risk by combining fuzzy comprehensive evaluation method.The results show that the pipeline risk level of a gas gate station in Shenyang is low.The model established in this paper is helpful to reduce the occurrence of pipeline accidents in urban gas gate stations and has important practical application value.
