  要:除雪防滑是我国北方地区高速公路冬季养护的重要任务之一,与交通安全和服务水平息息相关,四车道和六车道高速公路除雪工艺已经比较成熟,但对于多车道高速公路除雪工艺缺乏研究。本文针对客货分离式双向十二车道高速公路,分析多车道高速公路除雪防滑的难点,提出了中小雪、大雪和暴雪等雪情下的除雪工艺设计,重点阐述了客货分离式多车道高速公路客车道、货车道,以及特殊路段除雪要点和工艺,明确了机械除雪和人工步骤,为多车道高速公路除雪作业提供理论和技术支撑。

Abstract: Snow clearing and skid prevention is one important task of expressway maintenance in winter in northern China. It is closely related to traffic safety and service level. Now four-lane and six-lane expressway snow removal technology is relatively mature, but the research of multi-lane expressway snow removal process is very deficient. Aiming at the two-way twelve-lane highway with passenger and freight separation, this paper analyzes the difficulties of snow removal and anti-skid of multi-lane highway, puts forward the snow removal process design under the snow conditions of medium and small snow, heavy snow and heavy snow, and focuses on the passenger and freight separation of multi-lane highway bus lane, truck lane, and special road snow removal points and processes, and defines the mechanical snow removal and manual steps, providing theoretical and technical support for snow removal operation of multi-lane highway.
