高速公路建设期重大危险源辨识探讨

Discussion on Identification of Major Hazards during Highway Con-struction Period

文章基于危险源及重大危险源的一般定义,结合湖北杭瑞高速公路建设的实际情况,提出了高速公路建设期重大危险源的定义,并通过建立概率风险评价分析模型,采用事故树分析法和德尔菲法确定了事故发生的概率值,得出了判别重大危险源的风险度临界值,以对类似高速公路建设期重大危险源的辨识提供指导。

Based on the general definition of hazard and major hazard and combined with the real construction condition of Hangrui highway in Hubei,the article proposes the definition of hazard during highway construction period.Through building the analysis model of probability risk evaluation,the article also uses accident tree analysis method and the Delphi method to determine the probability of accidents and gets the critical value for the degree of risk,which provides reference to similar cases.
