| 摘 要： | 长大纵坡是山区高速公路中常见的行驶工况之一。由于山区高速公路中长大纵坡一般伴随着陡坡急弯、团雾多发、通视差等恶劣行车工况,在线形设计中必须引起高度重视;本文以长大纵坡的特殊车道设计为研究对象,根据不同行驶工况提出了相应的特殊车道设计原则和方式,明确了线形优化设计的基本流程,确保了长大纵坡路段的安全行驶。

| Abstract: | Large longitudinal slope is one of the common driving conditions in mountain highway.Because the large longitudinal Slope of mountain highway is usually accompanied by Steep slope and sharp bend、fog、parallax and other bad driving conditions,great attention must be paid to the linear design.In this paper,the design of special lane in the large longitudinal slope is presented.according to different driving conditions,Principles and methods of special lane design are put forward.The basic process of linear design is defined,Ensuring the safe driving of large longitudinal slope. |
