基于事故树的埋地燃气管道失效的原因的调查与统计分析

Investigation and Statistical Analysis of Failure Reasons of Buried Gas Pipeline based on Accident Tree

如今随着人们生活水平的提高,以及国家对天然气的开发与利用力度不断的提高,导致埋地燃气管道的数量不断增加。因此,基于事故树对埋地燃气管道失效原因的调查与统计分析对于燃气管道的利用有着重要的意义。在这里通过现场调研、问卷、文献资料等方式对城市燃气埋地燃气管道失效原因的调研,然后运用数理统计等方法建立埋地燃气管道失效原因事故树,归纳总结影响失效的主要原因,为后续管网运行维护提供科学的依据。

Nowadays,with the improvement of people's living standard and the national development and utilization of natural gas,the number of buried gas pipelines is increasing.Therefore,the investigation and statistical analysis of the failure reasons of buried gas pipelines based on the accident tree are of great significance for the utilization of gas pipelines.In this paper,the failure reasons of buried gas pipelines in cities are investigated by means of field survey, questionnaire,literature and other methods.Then,mathematical statistics and other methods are used to establish the accident tree of the failure reasons of buried gas pipelines and summarize the main reasons affecting the failure,so as to provide scientific basis for the subsequent operation and maintenance of pipeline network.
