Analysis and Countermeasures of Safety Accidents in Urban Gas Pipeline Networks

Abstract

Urban gas pipeline network is the lifeline engineering infrastructure of the city responsible for energy transmission. With the accelerated urbanization process, the construction of urban gas pipeline network has begun to expand rapidly. However, in recent years, due to the aging of some pipelines, third-party construction damage and other factors, urban gas pipeline network safety accidents have occurred frequently, causing huge casualties and property losses. Therefore, this paper analyzes the gas pipeline safety accidents that occurred this year. From the perspective of safe operation of urban gas pipeline network, with the purpose of improving its disaster bearing capacity and improving the safety resilience level of gas system, this paper comprehensively uses the combined weighting method to study the urban gas pipeline network system. Finally, according to the results of evaluation and analysis, specific improvement countermeasures are proposed from the three dimensions of pressure, state and response, which can better explain the process of resisting, digesting, reorganizing and optimizing the uncertain risks faced by gas pipeline network, and then achieving a dynamic stable state, which provides new ideas for disaster prevention of urban gas system.
