摘　　要：为了提升山区高速公路路线设计水平,从设计原则、设计环节、设计影响因素三方面总结了路线设计基本理论,探讨了路基土石方计算方法及路线设计指标对土石方调配、土石方工程量的影响。为了减少土石方开挖,对路堑方案和隧道方案进行综合比选。研究成果可为山区高速公路路线设计提供科学的理论指导。In order to improve the level of highway route design in mountainous areas,the basic theory of route design was summarized from three aspects:design principles,design links,and design influencing factors.The calculation method of roadbed earthwork and the influence of route design indicators on earthwork allocation and earthwork engineering quantity were discussed.Subsequently,in order to reduce earthwork excavation,a comprehensive comparison and selection of cutting and tunnel plans was conducted,and the research results can provide scientific theoretical guidance for the design of mountain expressway routes.
