摘要:

Na-Tech(natural-technological)事件是典型的HILP(high-impact low-probability)事件,近年来时有发生,尤其是在危险源高度集中的化工园区。Na-Tech事件演化过程和机理的高度复杂性,使其成为风险评价领域的研究难点。对Na-Tech事件统计文献进行分析,理清最频发的自然灾害类别、最脆弱的设备类型及其致损模式等特性和规律,进一步探究Na-Tech事件演绎过程,包括自然灾害和技术灾害。对当前文献中Na-Tech事件定量风险评价方法进行深入剖析,指出自然灾害与技术灾害的设备致损概率计算是其核心问题。从土地使用规划,设备完整性、鲁棒性与本质安全工艺,安全防护设施,安全教育、管理与合作,事故应急响应,灾后恢复与重建等六方面探讨了Na-Tech事件防控体系。指出自然灾害条件下的设备易损性和多致灾因子耦合作用是Na-Tech事件研究的突破方向,也是进行定量风险评价的关键环节。

Abstract:

Na-Tech event is a typical HILP (high-impact low-probability) event that has occurred in recent years, especially in Chemical Industry Park with high concentration of hazards. The complexity of the evolution process and mechanism of Na-Tech event makes it a difficult problem in the field of risk assessment. This paper first analyzes the Na-Tech event statistics literatures, clarifies the characteristics and laws of the most frequent natural disaster categories, the most vulnerable equipment types and their damage modes, and further explores the Na-Tech event deduction process, including the natural disaster and technical disaster. Then, the quantitative risk assessment methods for Na-Tech event in the current literatures are deeply analyzed, and it is pointed out that the calculation of equipment damage probability of natural disaster and technical disaster is the core problem. In addition, the Na-Tech event prevention and control system is discussed from six aspects: land use planning, equipment integrity, robustness and intrinsic safety technology, safety protection facilities, safety management, emergency response, post-disaster restoration and reconstruction. Finally, it is pointed out that the vulnerability of equipment under natural disasters and the coupling effect of multi-hazard factors are the breakthrough direction of Na-Tech research, and the key process of quantitative risk assessment.

Key words: pre-control system, quantitative risk assessment, Domino effect, Chemical Industry Park, Na-Tech event
