摘　　要：通过介绍燃气输配系统的组成、安全运行特点和北京市燃气管网构成,根据不同泄漏源和产生原因对近几年北京市燃气管网泄漏事故进行统计分析,得出人为破坏和腐蚀老化是导致城市地下燃气管道泄漏事故的主要原因。对引发泄漏的危险因素进行全面分析,并有针对性地提出城市地下燃气管网安全对策,为泄漏事故的预防提供理论指导。By introducing the composition of system of gas transmission and distribution, safety operation characteristics and gas pipe network of Beijing, it is obtained that the main cause of the urban underground gas pipeline leakage accidents are corrosion and artificial aging, through statistic analysis on the gas pipe network leakage accident in Beijing in recent years ac- cording to leakage source and different causes. Dangerous factors leading to leakage are compre- hensively analyzed, and safety countermeasures on the urban underground gas pipe network are put forward. This can provide theoretical guidance on the prevention of leakage accident.
