摘　　要：通过对运煤高速公路交通特性和选线考虑的要素分析,进行实例设计验证,以京新高速公路集宁至呼和浩特段为例,通过分析其作为主要运煤通道的线路位置及地形气候等因素,来选择合适的运煤高速公路设计方案。从经济性、技术性以及合理性进行综合对比,最终选取了阳坡路线方案、山坡路线方案以及隧道布设方案中的方案一。此外,还论证了长大下坡设计的合理性及安全性,并提出了可行的路面设计方案,论述了安全设施设计,为该路段的行车安全提供了保障。The transportation characteristics of the coal expressway and the factors considered in the route selection are analyzed to verify the design of an example. Taking the Jining to Hohhot section of the Jingxin expressway as an example, the location and terrain climate of the main coal transportation channel and other factors are analyzed to choose a suitable coal expressway design scheme. Through the comprehensive comparison of economy, technology and rationality, the sunny slope route scheme, hillside route scheme and reasonable tunnel layout scheme are finally selected. In addition, the rationality and safety of the long-and-large downhill design is demonstrated, and feasible road design schemes are proposed, and the design of safety facilities is discussed, which provides a guarantee for the driving safety of this section of the road.
