山区高速公路隧道群路段危化品运输风险评价体系研究

Risk evaluation for hazardous chemicals transportation at mountainous freeway with tunnels groups

以湖南雪峰山隧道群路段为研究对象,针对其严峻的危化品运输安全管理形势,调研事故路段特征、危化品运输信息及交通事故特征,构建交通安全评价模型。以该模型为基础,通过建立各要素修正因子库,构建危化品运输风险识别和风险值评价模型,提出危化品运输风险评价体系。研究结果表明:事故预测结果与实际结果较一致,事故识别与评价模型、评价原则共同构建的危化品运输风险评价体系具有一定的现实指导意义。

The Xuefeng Mountain tunnel of Hunan Province was taken as the researched object,the serious problem on safety management of hazardous chemicals transportation was dealt with.An intensive investigation on basic information of road,hazardous chemicals and accidents was firstly conducted.Then,the evaluation model of traffic safety was developed.Based on this model and correction factors of variables,the risk identification model and the risk value evaluation model of hazardous chemicals transportation were developed.Finally,the risk evaluation system of hazardous chemicals transportation was developed.The results show that the predicted accident rate agrees well with the actual accident rate,and thus the proposed risk evaluation system can guide the safety management of hazardous chemicals transportation on similar freeways.
