石家庄槐安路与西二环立交总体方案研究

石家庄市槐安路、西二环均是城市规划确定的快速路,但受建设条件限制,该快速交叉节点始终未形成互通。为解决周边急迫的交通问题,对现状道路及建设条件进行交通分析和功能定位,在现有用地条件限制下,提出两个立交方案。通过比选,推荐采用定向式立交方案,解决了拆迁问题。同时,通过优化匝道线形、敷设相变沥青等技术手段,解决了采光、路面冰冻等难题。一期工程通车后,实现了槐安路东侧主路与西二环的快速交通转换。

Research on Overall Scheme of Huaian Road and West Ring II Road Interchange in Shijiazhuang

Huaian Road and West II Ring Road in Shijiazhuang are all the expressways determined by urban planning. However, limited by the construction conditions, the rapid intersection node has not been interconnected. To solve the urgent traffic problems around, the traffic analysis and functional orientation are carried out for the present roads and construction conditions. Limited by the existing land conditions, two interchange schemes are proposed. Through the comparison and selection, the orienteering interchange scheme is recommended to solve the demolition problems. At the same time, by optimizing the ramp alignment and paving the phase change asphalt and using the other methods, the problems of lighting, pavement freezing and the others can be solved. The Phase I of the project opening for traffic can realize the rapid traffic conversion of the main road at the east side of Huaian Road and West Ring II Road.
