摘　　要：以兴国至赣县高速公路北延工程大沽枢纽互通立体式交叉工程设计为例,从互通选型、地方道路改移、加减速车道与端部设计及排水设计等方面提出了一些山区高速公路枢纽互通立体交叉设计的注意事项,为后续类似项目的设计提供一定的参考。Taking the design of the Dagu hub interchange of the Xingguo-Gan County Expressway North Extension Project as an example,some precautions for the interconnection and three-dimensional intersection design of mountain expressway hubs are proposed from the aspects of interconnection selection,local road relocation,acceleration and deceleration lane and end design and drainage design The design of subsequent similar projects provides some reference.

关 键 词：枢纽互通式立体交叉 变速车道 方案设计
