【摘要】：多米诺效应是导致石化企业火灾、爆炸及中毒事故后果扩大的根本原因,往往会引起事故损失成倍增长,而合理的平面布局设计可以大幅降低企业的多米诺效应风险。本文在前人研究的多米诺效应评估指标基础上,结合源发事故单元事故场景发生概率、多米诺事故扩展概率,以及目标单元事故强度等概念,构建了基于源发事故单元及目标单元多米诺风险的表征表达式,进一步构建了评估整体布局多米诺风险的评估指标并给出了具体的实施程序,用于评估单元和整个布局的多米诺风险。研究表明该法能够反映厂区布局多米诺特征,对于持续完善多米诺评估指标研究工作以及工程建设初期的布局草案筛选具有一定意义。
[Abstract]:Domino effect is the fundamental cause of the expansion of fire, explosion and poisoning accidents in petrochemical enterprises, which often leads to the multiple increase of accident losses, and reasonable layout design can greatly reduce the domino effect risk of enterprises. In this paper, based on the Domino effect evaluation index studied by predecessors, combined with the source accident unit accident scenario probability, domino accident expansion probability, and target unit accident intensity, etc. Based on the token expression of domino risk of source accident unit and target unit, the evaluation index of domino risk of whole layout is further constructed and the concrete implementation procedure is given. Domino risk used to assess the unit and overall layout. The study shows that this method can reflect the dominoes characteristics of plant layout and has certain significance for the continuous improvement of Domino evaluation index research and the screening of layout draft in the initial stage of construction.
