摘要：
This paper provides a method of semi-quantitative risk assessment for urban gas pipelines, by modifying Kent analysis method. The influence factors of fault frequency and consequence for urban gas pipelines are analyzed, and the grade rules are studied on. The grade rules of fault frequency and consequence for urban natural gas pipelines are provided. Using semi-quantitative risk matrix, the risk grade of the urban gas pipelines is obtained, and the risk primary sort for gas pipelines can be accomplished, so as to find out the high risk pipeline unit.
