Abstract

With the acceleration of urbanization and the continuous expansion of gas pipeline networks in Chengdu, natural gas leakage accidents caused by extreme weather, complex terrain, third-party construction damage, and other extreme scenarios occur frequently, posing severe threats to urban public safety, residents’ lives and property, and the ecological environment. The current emergency response and rapid repair mechanisms for natural gas leakage in Chengdu still suffer from insufficient targeted contingency plans, poor emergency coordination, inadequate adaptability of technical equipment, and uneven professional capabilities of repair teams, which can hardly fully meet emergency response demands under extreme scenarios. Based on the characteristics of Chengdu’s gas pipeline network distribution, types of extreme scenarios, and current emergency response status, this paper analyzes typical cases and existing shortcomings, and puts forward targeted optimization suggestions from five dimensions: optimization of the contingency plan system, improvement of the coordination mechanism, upgrading of technical equipment, strengthening of team building, and improvement of the support system. The aim is to enhance the efficiency of emergency response and rapid repair of natural gas leakage in Chengdu under extreme scenarios, build a solid line of defense for urban gas safety, and provide theoretical support and practical references for Chengdu’s construction of a safe and resilient city.
