Fuzzy Comprehensive Assessment of Urban Underground Power Cable Infrastructure Safety Risk

The power cable is one of the most important infrastructures, which safety and reliability is of an important significance to the stability and development of urban. To the safety risk features of urban power cable infrastructure, this paper proposed the safety risk evaluation index system and quantitative identification method based on analyzing the composition and construction features, and established the fuzzy comprehensive evaluation model of underground cable infrastructure safety risk. A case study shows that this method is feasible, and consistent with the practical construction, and proposed the measures to prevent the occurrence of major hazards.
