榆科枢纽互通式立交方案研究

Research on Scheme of Yuke Interchange Overpass Pivot

榆科枢纽互通是大广高速与石黄高速交通流转换的重要枢纽互通,考虑大广高速公路榆科枢纽交通量的分布情况后,确定了交通功能和等级。针对本工程既有在建项目,又有近、远期规划项目的特点,确定了该互通式立体交叉的主要问题,寻找出满足功能、易于实施、减少投资、在总体建设规模上降低工程造价的可行方案。

Yuke pivot interchange is very important for traffic flow transfer between Daguang Expressway and Shihuang Expressway.After considering of traffic distribution of Yuke pivot of Daguang Expressway,traffic function and grade are determined.As this project has not only one in progress,but also short and long term planning ones,the main problems of interchange are determined.The feasible scheme for the satisfaction function,the convenience of implementation and investment reduction as well as project cost reduction of total construction scale can be found out.
