宜昌市港窑快速路总体方案研究

Study on Overall Scheme of Gangyao Expressway in Yichang

对宜昌市港窑快速路进行了总体方案研究。从功能定位出发,根据项目的建设条件和限制因素,进行交通分析和交通量预测。路线方案选择时,结合山岭重丘区的特点,先比选论证路线走向,再进行线位比选,确定推荐线位。根据道路沿线地形地貌、规划用地属性等因素确定道路横断面型式。对沿线相交的重要道路(峡州大道、东城大道、东方大道、小鸦公路、宜黄公路等)进行节点方案研究,共设置7处互通立交,较好地解决了港窑路与沿线路网的衔接与交通转换。

This paper studies the overall scheme of Gangyao Expressway in Yichang, and based on the construction condition and limiting factor of the project, carries out the traffic analysis and the traffic flow forecast from the functional localization. According to the characteristics of the mountainous and hilly areas,the line alignment is firstly compared and demonstrated, then the line location is compared and selected, and finally the line location is recommended during the comparison of line scheme. Based on the factors of topography and landform along the line, and the property of planned land, the cross section type of road is determined. The node schemes of the important roads(Xiazhou Avenue, Dongcheng Avenue, Dongfang Avenue, Xiaoya Highway and Yihuang Highway) intersected along the line are studied. There are seven interchanges, which better solve the connection and traffic conversion of Gangyao Road with the road network along the line.
