摘　　要：高速公路是打通山区对外发展的重要通道,而互通立交是山区高速公路的关键节点,其位置的选择与互通形式的确定是山区高速公路设计过程中需关注的重点和难点。以浙中南山区义龙庆高速公路义乌至龙泉段(金华段)桃溪互通为例,综合考虑转向交通量、线形指标参数、地形地物、工程规模、空间利用、投资成本、施工难易程度等因素,对常规互通立交方案和异形互通立交方案进行同深度综合比选,通过定性和定量分析,最终拟定更能适应山区地形的异形喇叭互通方案作为推荐方案,为能因地制宜地进行山区高速公路互通立交设计,支持互通选型多样化提供了思路。Highways are important channels for the external development of mountainous areas.As key nodes of mountainous highways,the selection of interchange locations and the determination of interchange types are key and difficult points that need to be paid attention to in the design process of mountainous highways.The article took the Taoxi Interchange of Yiwu-Longquan section(Jinhua section)of the Yilongqing highway in mountainous areas of central and southern Zhejiang Province as an example.Taking into account factors such as turning traffic volume,linear index,terrain and land features,project scale,space utilization,investment cost,and construction difficulty,a comprehensive comparison of conventional and heterotypic interchange schemes was conducted at the same depth.Through qualitative and quantitative analysis,a heterotypic variant horn shaped interchange scheme that is more suitable for mountainous terrain is ultimately recommended,providing ideas for designing interchanges on mountainous highways according to local conditions and supporting diversified interchange selection.
