太旧高速公路旧街枢纽立交改造方案研究

Study on Transformation Scheme of Jiujie Hub Interchange of Taijiu Expressway

旧街枢纽立交是连接太旧高速与阳泉绕城高速交通转换的重要节点,旧街枢纽改造方案受既有高速主线、匝道线形、桥梁跨径、周边村庄、被交道路及运营保通等因素影响较大,在拟定旧街枢纽改造方案时,结合项目总体思路,详细研究既有立交方案,经多方案综合比选,合理控制项目改造规模,择优推荐,确保项目的顺利实施。

The Jiujie hub interchange is an important joint in the traffic conversion of Taijiu Expressway and Yangquan Belt Expressway,and its transformation scheme is greatly affected by factors of the existing main route,ramp alignment,surrounding villages,crossed roads,and smooth operation.While determining the transformation scheme of the Jiujie hub,combined with the overall concept of the project,this paper detailedly investigated the existing interchange schemes.After the comprehensive selection of multiple schemes,the transformation scale of the project was reasonably controlled and the optimum scheme was recommended to ensure the smooth implementation of the project.
