摘　　要：事件树分析法的研究步骤包括确定初始事件、环节事件,绘制、分析事件树图。建立了大型化工企业消防系统地震灾害风险评价模型,研究了单元火灾与损失震害形态、单元间延烧与控制对策。增加无震害环节事件概率,减少有震害环节事件概率是消防系统地震风险分析与控制的重要研究方向。消防水源多样化、减少消防系统震害损伤、增加消防能力有助于降低消防系统的地震灾害风险。The research procedures of event tree analysis are to determine the initial event, list events in the vent, spreading fire between varied units and control measures. It is a research orientation in seismic risk analysis and control of fire-extinguishing system to increase the probability of non-seismic events and decrease the probability of seismic events in the process. It helps to reduce the seismic risk by obtaining water to fight fire from various sources, minimizing the damage of the fire-extinguishing system caused by seismic events and enhancing the ability to fight fire.
