摘要

多米诺骨牌效应在工业中引发的事故危害极大。本研究旨在分析多米诺骨牌效应在化工储罐可能发生爆炸和火灾情况下的发生概率。利用以往的研究结果，回顾过去的事故，并根据设备损坏模型，采用提取工艺设备和固有安全距离的阈值作为防止多米诺骨牌事故的标准。根据主要情景和实验方程，确定了不同储罐的升级矢量。根据火灾半径等同于固有安全距离的假设，计算出 1 号油罐的火球半径为 535.7 米。根据计算结果，3 号油罐的 DCP 指数可视为最危急单元。本研究根据标准和危险指数参数研究了多米诺骨牌效应的发生概率和预防方法。

Studying Probability of Domino Effect in Chemical Storage Tanks Using Hazard Index

The accidents caused by the domino effect in industries are highly harmful. This study aims to analyze the occurrence probability of the domino effect with respect to possible explosion and fire scenarios in chemical tanks. Using the results obtained by previous studies, reviewing past accidents, and according to the equipment damage models, threshold values were used for extraction process equipment and inherent safety distances as a criterion to prevent domino accidents. According to primary scenarios and experimental equations, the escalation vector was determined for different tanks. According to the assumption that fire radius is equivalent to inherent safety distance, the fireball radius for tank 1 was calculated 535.7 m. According to the results, the DCP index of tank 3 can be considered the most critical unit. This research studies the probability of the domino effect and means to prevent them according to criteria and hazard index parameters.
