摘要
为了准确、快速地判识危化品重大危险源厂界外部群体建筑物的抗爆安全风险,首先,从城市灾害风险系统理论与灾害风险管理理念出发,综合考虑爆炸危险性、爆炸易损性、抗爆安全能力和抗爆应急能力四个评估维度,建立群体建筑物抗爆安全风险评估指标体系;其次,构建基于可拓联系云的抗爆安全风险评估模型,消除多种风险信息交叉融合产生的不确定性,定量评估群体建筑物的抗爆安全风险等级;最后,评估流程应用于某市爆炸类危化品重大危险源企业的外部群体建筑物,结合可视化方法系统评估了群体建筑的抗爆安全风险.结果表明:该方法能够快速有效地评估群体建筑物的抗爆安全风险水平,可靠直观地反映群体建筑物抗爆性能的薄弱环节,为重大危险源企业外部群体建筑物的抗爆安全规划建设提供决策支撑.
Abstract
In order to accurately and quickly identify the anti-explosion safety risk of the group buildings outside the plant boundary of the major hazards,firstly,based on the urban disaster risk system theory and disaster risk management concept,an anti-explosion safety risk assessment index system of group buildings was established.The four assessment dimensions include explosive hazard,explosive vulnerability,anti-explosion safety capacity and anti-explosion response capacity.Secondly,an anti-explosion safety risk assessment model based on the extension connection cloud is constructed.It eliminates the uncertainty generated by the cross-fertilization of multiple risk information and realizes the quantitative assessment of the anti-explosion safety risk level of group buildings.Finally,in order to verify the effectiveness of the assessment methodology,the assessment process is applied to group buildings outside the major hazards of explosives-type hazardous chemicals in a city.The results show that the method can quickly and effectively assess the level of anti-explosion safety risk of group buildings.The method reliably and intuitively reflects the anti-explosion deficiencies of group buildings.It provides decision-making support for the anti-explosion safety planning and construction of group buildings outside major hazards enterprises.
