摘要: 为提高站场储罐区的应急响应和风险防控能力,通过对比扩展向量和失效阈值,确定了不同事故类型下的多米诺效应传播路径,通过贝叶斯网络并引入辅助节点提取不同层级多米诺效应概率,以某站场储罐区为研究对象完成了实例分析。结果表明,位于罐区角落且处于上风向的储罐发生火灾时,多米诺效应的传播路径最广;位于罐区中间位置的储罐在发生爆炸时,超压危害波及的范围更大,危险性更高。研究结果可为防灾减灾措施的制定提供理论依据。

Abstract: In order to improve the capability of emergency response and risk prevention and control in the storage tank area of the station yard, the domino effect propagation path under different accident types was determined by comparing the extension vector and failure threshold. The probability of domino effect at different levels was extracted by using the Bayesian network and introducing auxiliary nodes, and the case analysis was completed by taking the storage tank area of a station yard as the research object. The results show that the propagation path of domino effect is the widest when the fire occurs in the storage tank located at the corner of the tank farm and in the upwind direction. When the storage tank located in the middle of the tank farm explodes, the tanks are more dangerous in the event of an explosion, as the overpressure hazard is more widespread. The results can provide a theoretical basis for the formulation of disaster prevention and reduction measures.
