摘要
随着国家一带一路战略的实施,加强了各地交通建设,推动了产业发展,特别是山区加快构建了对外通道,完善内部路网.山区高速公路的建设过程中普遍存在地形陡峭、地质复杂、施工难度高、投资造价贵等问题,相比一般地区高速公路设计难度更大.因此,山区高速公路选线的科学性合理性尤为重要,通过对路网布局、项目功能、工程规模及区域协调4个方面进行研究,结合重庆市南川区合大高速实例进行选线,为类似工程提供借鉴意义.
With the implementation of the Belt and Road Initiative of the nation,the transportation construction in various regions has been strengthened to promote industrial development,especially in mountainous areas,the construction of external channels has been accelerated and the internal road network has been improved.In the process of expressway construction in mountainous areas,there are many problems,such as steep terrain,complex geology,high construction difficulty and high investment cost.Compared with ordinary areas,the design of expressway in mountainous areas is more difficult.Therefore,the scientific rationality of expressway route selection in mountainous areas is particularly important.Through the research on road network layout,project function,project scale and regional coordination,the route selection is carried out in combination with the example of Heda Expressway in Nanchuan District,Chongqing province,so as to provide reference for similar projects.
