城市燃气管道风险评价研究

Research on risk assessment of urban gas pipelines

概述了近二十年国内外管道风险评价的研究背景和现状,对城市燃气管道风险评价的基本步骤、重要事故风险指标的计算和风险评价准则进行了总结,以某城镇燃气管道为例,利用Phast软件计算了重要事故的伤害面积指标,并对结果进行了分析,最后对国内风险评价方法提出不足和展望。

Summarizes the research background and research status of pipeline risk assessment in the past two decades,summarizes the basic steps of urban gas pipeline risk assessment,the calculation method of accident consequences,and risk assessment criteria.Take a town gas pipeline as an example,Phast software was used to calculate the damage area of important accidents,and the results were analyzed.Finally,the shortcomings and prospects of domestic risk assessment methods are put forward.
