摘要

郊区高速公路的特殊区位,决定其互通式立交具有鲜明的特点。如何进行复杂的路网衔接和场地控制是郊区高速公路互通式立交面临的重要问题。郊区高速公路互通式立交设计应从节点选择、间距控制、匝道布设等方面入手,处理好衔接方式、立交构型、匝道类型等问题,实现安全、高效、便捷的建设目标。
        The special location of expressway in suburb determines that its interchange has distinct characteristics. How to carry out complex road network connection and site control is an important problem faced by the expressway interchange in suburb. The design of expressway interchange in suburb should be started from node selection, spacing control and ramp layout and so on, so as to deal with the problems of connection mode, interchange configuration and ramp type and achieve the goal of safe, efficient and convenient construction.
