北京市燃气管网危险因素的事故树分析

Fault Tree Analysis on Risk Factors of Underground Gas Networks of Beijing City

    摘要
  • 摘要: 对北京市近六年来发生的燃气管网事故进行了统计, 结果表明, 管道泄漏是北京市燃气管网事故的主要原因。利用事故树分析法对管网泄漏的危险因素进行了分析, 分析结果认为, 管网泄漏事故多由外力破坏、腐蚀老化和安装缺陷所致。提出了燃气管网的安全防范措施, 以增加管网系统运行的安全性和可靠性。

     

    Abstract: Accident statistics on the underground gas networks in recent 6 years in Beijing City is carried out and the result shows that pipeline leakage is the main cause of accident.Analysis on risk factors of networks leakage is made with fault tree method.Analyzing results show that the leakage accidents of gas pipeline networks are most induced by third party's damage, corrosion or aging of pipe and installation defects.Safety and protection measures for the underground gas networks are proposed in order to increase operation safety and reliability for gas networks system.
