摘　　要：山区高速公路受地形限制,互通立交和服务区的布设形式往往更加复杂,从功能需求和工程投资角度出发,可考虑互通立交与服务区合并设计。以湖南山区某高速公路高坪互通与高坪服务区的组合方案设计为例,根据地形地质条件、交通流向、现有路网、村庄分布等情况,对互通与服务区合并设计的方案进行了探讨,确定了较优的设计方案,可为同类工程项目提供参考。Restricted by the terrain,the layout of interchanges and service areas of mountainous highways are complex.In terms of functional requirements and engineering investment,it is considered that merging the interchange with the service area.Based on the merging design of Gaoping Interchange and Gaoping Service Area in a mountainous highway in Hunan Province,this paper discussed the merging schemes according to the topographic and geological conditions,traffic flow direction,existing road network,village distribution,and other situations,and determined an optimal design scheme,which can provide a reference for similar engineering projects.
