摘　　要：为探析环线高速公路既有三岔T型互通改扩建方案选型和匝道连接方式,依托百色南环线高速公路节点枢纽上宋互通改扩建工程方案的研究实践,从路网形态特征、交通适应性、技术条件等方面分析枢纽互通的选型因素,进行互通总体方案的比选,并提出了改扩建互通较为新颖的匝道连接设计方式,研究结果可为类似项目设计提供指导。In order to explore the selection of existing T-type interchange reconstruction and expansion scheme and ramp connection mode of ring expressway,based on the research and practice of Shangsong interchange reconstruction and expansion project scheme of Baise south ring expressway node hub,this paper analyzes the type selection factors of hub-and-spoke interchange from the aspects of road network shape characteristics,traffic adaptability and technical conditions,and compares and selects the overall type design scheme of hub-and-spoke interchange.A new design method of ramp-way connection is put forward,which can provide guidance for similar project design.
