朱圩子互通立交枢纽的设计

Design of Zhuweizi interchange

朱圩子互通立交枢纽是连云港—霍尔果斯、北京—福州两条国道主干线高速公路相交叉的重要交通枢纽 ,并与地方干线公路网相连。该立交是安徽省目前规模最大的互通立交 ,属系统性互通立交。其设计受到特定的路网规划 ,复杂的地形、工程地质等条件的限制。立交总占地 10 5 .7hm2 ,设有大桥 7座、中小桥 11座。文章较系统地介绍了该互通立交的设计。

Zhuweizi interchange is the important interchange of the two principal arterial highways Lianyungang Huoerguosi freeway and Hefei Xuzhou freeway and the district highway network,and it is the largest freeway interchange in Anhui Province at present. Design of the interchange is constrained by highway network planning, complicated landform and engineering geological conditions. The interchange occupies 105.72 hectare,including 7 big bridges and 9 middle or small bridges.A detailed exposition of the interchange design is given in the paper.
