As a means of risk prevention and control management,the risk assessment of water supply pipe network can provide data support for the pre-engineering measures of pipe network and realize risk prevention.This paper introduces three risk assessment models of water supply pipe network,and selects a certain area in Shanghai to carry out risk assessment of water supply pipe network based on Shanghai local standard Technical Specification of Safety Risk Assessment for Urban Water Supply Pipelines Network(DB31/T 1332-2021)and the characteristics of water supply pipe network in this area.Combined with the risk assessment results and the actual situation of the pipe network in the target area,the assessment model is optimized to further improve the reliability of the assessment results.
