摘　　要：本文通过分析贵阳环城高速公路道路环境特征、地理特征及气候特征,确定了高速公路凝冻路段危险性影响因素,构建了高速公路易凝冻路段的凝冻危险性评估模型,并对评估模型进行了实例验证,结果表明:本模型能够准确地实现高速公路易凝冻路段的危险性评估,在此基础上,以贵阳环城高速道路结构、凝冻背景资料等为数据支撑,对环城高速公路的易凝冻路段进行了危险性评估和等级划分,为经营管理单位实现精细化的凝冻处置工作提供理论支撑,对进一步优化经营管理单位的“抗凝保通”工作具有重要的指导意义。By analyzing the environmental characteristics,geographical characteristics and climatic characteristics of the roads around the city of Guiyang,this paper determines the factors that affect the risk of the freeway-freezing sections,constructs the freeway-freezing risk assessment model,and verifies the assessment model with an example.The results show that the model can accurately realize the risk assessment of freeway-freezing sections.On this basis,Based on the structure of Guiyang Ring Expressway and the background information of freezing,the risk assessment and classification of the sections prone to freezing of the Ring Expressway are carried out,which provides theoretical support for the operation and management unit to realize the refined freezing treatment work,and has important guiding significance for further optimizing the“anticoagulation and traffic protection”work of the operation and management unit.
