枢纽互通式立体交叉采用完全立体交叉型,以保证所有交通流均为自由流.出入交通流在交叉公路上的接入形式以分合流为主,保证直行交通流具有绝对优先权.针对枢纽互通本特点,现就设计中如何针对所处地形、地质、路网等条件提出经济合理的建设方案这一问题,以某互通为例,介绍互通立交设计原则,结合交通量预测,对该立交进行方案比选,以期指导类似设计.
樞紐互通式立體交扠採用完全立體交扠型,以保證所有交通流均為自由流.齣入交通流在交扠公路上的接入形式以分閤流為主,保證直行交通流具有絕對優先權.針對樞紐互通本特點,現就設計中如何針對所處地形、地質、路網等條件提齣經濟閤理的建設方案這一問題,以某互通為例,介紹互通立交設計原則,結閤交通量預測,對該立交進行方案比選,以期指導類似設計.

The fully three-dimensional model is used for hub interchange to ensure that all traffic flow is free flow. The access form of entrance and exist traffic flow on cross road is given priority to convergence to ensure straight traffic flow has the absolute priority. For characteristics of hub exchange, economic and reasonable construction scheme is put forward on the conditions, such as topography, geology, road network and so on, and the interchanges design principles were introduced, taking one interchange for example, combined with the traffic volume prediction, schemes of interchange were compared, in order to guide the similar design.
