石家庄市中华大街与北三环互通立交设计

Design of Interchange between Zhonghua Street and North Third Ring Road in Shijiazhuang City

摘要:

石家庄市北三环市政化改造项目启动，石太高速公路、黄石高速公路在三环内的部分被命名为“北三环”，中华大街与北三环节点作为规划枢纽立交成为此次改造的关键节点。节点北侧紧邻西环铁路线，南侧紧邻高标准行洪通道及高层建筑，周边用地条件受限。结合建设条件，给出多个互通立交设计方案，通过交通功能、工程投资、水利防洪等方面的综合比选，确定立交总体设计方案。

Abstract:

With the launch of the municipal renovation project of the North Third Ring Road in Shijiazhuang, the internal parts of the Shitai Expressway and Huangshi Expressway have been named "North Third Ring Road", and the intersection of Zhonghua Street and North Third Ring Road as the planning hub has become a key node in this renovation. The north side of the node is adjacent to the railway route of West Ring, its south side is adjacent to high-standard flooding passage and high-rise buildings, and the surrounding land use is limited. Combined with the construction conditions, the multiple interchange design schemes are proposed. The overall design scheme of the interchange is determined through comprehensive comparison and selection of transportation functions, engineering investment, water conservancy and flood control.
