摘要
随着我国路网体系的完善,复杂地形地质条件下的山区高速公路建设愈加广泛。探讨了山区高速公路线路选型的方法和原则,并分析了开展线路设计的主要内容及设计要点,包含平面线形、纵面线形和线路交叉口。最后结合实际工程,分析了处于山区环境的高速公路线形设计的关键问题。
Along with the perfection of road network system in China, the construction of mountain expressway is increasingly wide under the complex topography and geological conditions. This paper further discusses the methods and principles of route selection of mountain expressways, analyzes the main contents and critical points of route design including the plane alignment, vertical alignment and route intersections, and analyzes the key problems existing in the route design of expressways located in the mountain environment by the practical engineering cases.
