利川至咸丰高速公路起点互通方案研究

Research on Interchange Scheme at Starting Point of Lichuan-Xianfeng Expressway

在新建高速公路与既有高速公路进行对接时,需对原互通进行相应改造。如何尽可能利用既有工程来减少损失并降低社会影响,是互通改造设计的重点和难点。为此,结合具体工程实例,对起点互通改造提出了几种方案进行比选,并推荐最优方案,以期为类似项目建设提供借鉴。

The original interchange should be relevantly reconstructed when the new expressway and the existing expressway are connected together. It is important and difficult how to utilize the existing projects as far as possible to decrease the loss and reduce the influence on the society. Therefore, combined with the practical engineering cases, this paper puts forward and compares several schemes for reconstruction of interchange at starting point, and recommends the optimal scheme in order to provide the reference for the construction of the similar projects.
