西藏高原地区高速公路路面结冰状态关键控制因子确定

Determination of the key control factors of highway icing state in Tibet plateau

针对西藏高原地区高速公路路面结冰对行车安全造成的影响,从路面结冰的原理和阶段,多角度分析路面结冰的影响因素,得出路面结冰的条件、类型和特征。根据分析结果,设定路面结冰试验的控制参数,通过室内试验研究观测路面结冰状态的形成过程和规律,最终确定路面结冰状态的关键控制因子。

In view of the influence of highway icing on traffic safety in Tibet plateau area,this paper analyzes the influencing factors of pavement icing from the principle and stage of pavement icing,and obtains the conditions,types and characteristics of pavement icing.According to the analysis results,the control parameters of the road icing experiment are set,the formation process and law of the road icing state are observed through the indoor experiment,and the key control factors of the road icing state are finally determined.
