摘要
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。
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.
