基于事故树分析法的长输管道泄漏因素分析

泄漏是长输管道的典型事故,也是引起其他一些事故的重要原因。通过运用事故树分析法对长输管道泄漏问题进行定性和定量分析,可以识别引起长输管道泄漏的主要因素。通过构建管道泄漏事故树,求解重要度、事故发生概率和临界重要度,形成基于事故树分析的长输管道泄漏因素分析方法,能为更好地实施长输管道安全管理提供重要依据。

Analyses on the leakage Fuctors of long-distance Pipelines Based on the Fault-tree Analysis Method

Leakage is not only a typical accident of long-distance pipeline, but also an important cause resulting in some other accidents. By applying the fault-tree analysis method to qualitative and quantitative analysis about leakage of long-distance pipeline, primary factors leading to pipeline＇s leakage can be identified. Fault-tree for pipeline leakage is structured, and important degree, probabilities of accident and critical important degree are solved. Thus the factor analysis method for leakage of long-distance pipelines is formed based on fault-tree analysis method, which can be taken as an important basis in carrying out perfect safety management for long-distance pipelines.
