摘　　要：随着我国公路建设的蓬勃发展,山区高速公路的修建越来越多,山区高速公路的设计任务也越来越重。路线方案设计的质量决定着工程的造价,后期工作展开的难易程度以及道路的安全耐久性,在整个道路建设过程中扮演着重要角色。为此,文章主要通过研究路线设计的影响因素、具体的路线设计方案,并结合工程实例对山区高速公路路线设计进行了研究。最终得出了地形和地势、不良地质、环保和地方规划以及工程造价对山区高速公路路线设计的影响,有效地控制了工程造价,保证了道路的安全耐久性以及与环境相协调的问题。With the rapid development of highway construction in China,there are more and more mountain expressways have been built,and the design task of mountain expressways is heavier and heavier.The quality of route scheme design determines the cost of the project,the difficulty of later work,and the safety and durability of the road,which plays an important role in the whole road construction process.Therefore,this paper mainly studies the influencing factors of route design,the specific route design scheme and the engineering examples.Finally,the influence of topography,unfavorable geology,environmental protection,local planning and project cost on the design of highway route in mountainous area is obtained.It is benefit to control the project cost effectively,ensure the safety and durability of the road coordinating wit h the environment.
