宜宾二二四交通节点改造方案研究

Study on Reconstruction Scheme of Yibin 224 Traffic Node

宜宾二二四节点(翠柏大道与岷江大道交汇)作为宜宾市叙州区对外门户,现状交通拥堵严重。在节点交通量调查和沿线控制建筑分析的基础上,提出了2条主干路建设规模和翠柏大道跨线桥长短通道方案。其中的总体方案综合考虑交通功能、旧城改造情况、远期智轨线路和车站布设等因素按近远期实施;同时对岷江大道跨铁路、宜宾玻璃厂节点,提出了采用箱涵顶进方式进行扩容和预留跨线桥实施条件等改配建方案。

As the external gateway of Xuzhou District in Yibin City,the current situation of traffic at 224 Node of Yibin(intersection of Cuibo Avenue and Minjiang Avenue)is seriously congested.Based on the investigation of node traffic volume and the analysis of control buildings along the route,the construction scale of two main roads and the long and short channel scheme of Cuibo Avenue Overpass Bridge are put forward.The overall plan takes into account the traffic function,the old city reconstruction,the long-term intelligent rail transit,the station layout and so on,and will be implemented in the short term and long term.At the same time for the nodes of Minjiang Avenue crossing the railway and Yibin Glassworks,the reconstruction scheme of the box culvert jacking method used for expanding the capacity and reserving the implementation conditions of overpass bridge is proposed.
