摘　　要：为提升危化品道路运输风险评估的准确性,运用轨迹交叉事故致因理论,从危化品道路运输全路段的人员素质、运输装备、危险货物、安全管理及环境条件等方面分析事故致灾机理,构建风险量化评估指标体系,提出风险指数综合评估数学模型,完善并修正风险分级指数法的路径影响因子与安全补偿因子.通过实例分析不同路段组成的16条运输路径的风险特性和综合风险指数,获得了最佳运输路径.结果表明:改进的风险分级指数法能更加客观地反映危化品道路运输风险,为事故预防与控制提供了方法与思路.In order to improve the accuracy of risk assessment for road transportation of hazardous chemicals,the theory of trajectory intersection accidents was used to analyze the disaster mechanism of the accident from the quality of personnel,transportation equipment,dangerous goods,safety management and environmental conditions of the entire section of road transportation of hazardous chemicals.A risk quantitative evaluation index system was constructed,a comprehensive risk index evaluation mathematical model was put forward,the path impact factor and safety compensation factor of the risk classification index method was improved and modified.By analyzing the risk characteristics and comprehensive risk index of 16 transport routes composed of different road sections by example,the best transportation path was obtained,and the results show that the improved risk grading index method more objectively reflects the road transportation risks of hazardous chemicals,and provides methods and ideas for accident prevention and control.
