化工园区地震Na-Tech事件快速风险评估方法

为有效评估地震灾害与化工园区工业事故的耦合风险,在分析地震灾害作用于化工园区致灾特征的基础上,理清化工园区的主要承灾体类型,辨识出地震破坏承灾体单元后引发的火灾、爆炸、中毒等工业事故的主要影响因素,采用层次分析法(AHP),提出综合考虑地震灾害与工业事故耦合作用的Na-Tech事件快速风险评估方法。该方法以化工园区企业为评估单位,根据评估结果划定企业Na-Tech事件风险等级,并将此方法应用于某化工园区企业的风险评估。结果表明:该方法可操作性强,计算所需数据量小,且能有效反映地震Na-Tech事件风险特点。

Rapid risk assessment method for chemical industry park earthquake Na-Tech event

In order to effectively evaluate coupling risk of earthquake disaster and industrial accidents in chemical industry park,based on analysis of characteristics of earthquake disasters in chemical industry parks,main disaster-bearing body types were clarified in chemical industry park and main influencing factors such as fire,explosion,and poisoning were identified that caused by earthquake damage to a disasterbearing body unit using AHP,a rapid risk assessment method for Na-Tech event that comprehensively considers coupling effect of earthquake disasters and industrial accidents was proposed.This method takes chemical industry park enterprises as evaluation unit,risk level of enterprise Na-tech event was delimited according to evaluation results,and this method was applied to risk assessment of an enterprise in a chemical industry park.The results show that this method is feasible,the amount of data required for calculation is small,and it can effectively reflect risk characteristics of earthquake Na-tech events.
