发布时间：2019-04-30 07:32
【摘要】：随着我国经济的快速发展，天然气在能源领域的比重越来越高，在很多行业已经逐步取代了石油、煤矿等传统能源，成为了当今社会发展的新型能源。天然气是一种清洁能源，污染小，环境保护程度高，利用率高，在很多行业已经占据了主导的地位，随之各种天然气相关事故时有发生，给人民的生命财产安全带来了极大的隐患。天然气事故一般会有爆炸和火灾的危险，事态不易控制，很难进行有效的应急救援工作。城市天然气事故多由于管道出现问题而发生，有的天然气管道埋于地下，各种线路管道情况复杂，更不便于检查监控，所以要采取有效的安全管理措施，防患于未然，进行科学的风险分析和风险评价，对城市天然气管道的危险源进行处理，最大可能的防止城市天然气管道的泄漏、爆炸、火灾，最大程度的保障人民的生命和财产安全。 本文首先阐述了城市天然气的发展情况进行了简单的介绍，接着对城市天然气管道的安全隐患进行了分析，介绍了天然气管道事故的事故特点，介绍了风险与风险管理，然后研究了管道安全评价技术，最后通过定性的事故树分析法和半定量的灰色模型评价法对城市天然气管道事故进行了风险评价和安全性的分析，最终得出了相应的安全防范措施和数据分析结论，提高了城市天然气管道的安全程度。 基于以上的理论分析，本文以城市天然气管道为研究对象，利用事故树分析法和灰色理论GM(1,1)模型分析法进行风险评价。本文的研究能够为预防、评价城市天然气管道事故提供可靠的理论基础和一些相关的数据，有利于进一步的对天然气管道事故进行风险评价的研究，加快天然气管道风险评价的发展，保障城市天然气管道的正常运行。
[Abstract]:With the rapid development of China's economy, the proportion of natural gas in the field of energy is getting higher and higher. In many industries, natural gas has gradually replaced the traditional energy sources such as petroleum, coal mines and so on, and has become a new type of energy for the development of the society today. Natural gas is a kind of clean energy, with low pollution, high environmental protection and high utilization ratio. It has occupied a dominant position in many industries, and various natural gas-related accidents have occurred from time to time. It has brought great hidden trouble to the people's life and property safety. Natural gas accidents usually have the danger of explosion and fire, the situation is not easy to control, and it is very difficult to carry on the effective emergency rescue work. Urban natural gas accidents often occur because of problems in pipelines, some natural gas pipelines are buried underground, the situation of various lines and pipelines is complex, and even less convenient for inspection and monitoring, so effective safety management measures should be taken to prevent accidents in the near future. Scientific risk analysis and risk assessment are carried out to deal with the dangerous sources of urban natural gas pipelines so as to prevent the leakage explosion and fire of urban natural gas pipelines to the maximum extent to ensure the safety of people's lives and property. In this paper, the development of urban natural gas is introduced briefly, then the hidden danger of urban natural gas pipeline is analyzed, the accident characteristic of natural gas pipeline accident is introduced, the risk and risk management are introduced, and the safety hidden trouble of urban natural gas pipeline is analyzed, and the accident characteristic of natural gas pipeline accident is introduced. Finally, the risk assessment and safety analysis of urban natural gas pipeline accidents are carried out by means of qualitative fault tree analysis and semi-quantitative grey model evaluation, and the safety of urban natural gas pipeline accidents is analyzed by means of qualitative fault tree analysis and semi-quantitative grey model evaluation. Finally, the corresponding safety measures and data analysis conclusions are drawn, and the safety degree of urban natural gas pipeline is improved. Based on the above theoretical analysis, this paper takes the urban natural gas pipeline as the research object, uses the accident tree analysis method and the grey theory GM (1,1) model analysis method to carry on the risk assessment. The research in this paper can provide a reliable theoretical basis and some relevant data for the prevention and evaluation of urban gas pipeline accidents, which is conducive to the further study on the risk assessment of natural gas pipeline accidents. Speed up the development of natural gas pipeline risk assessment to ensure the normal operation of urban natural gas pipeline.
