Study on Design Schemes of Interchange Bridge Spanning Expressway

为了解决城市主干路跨越高速公路互通的难题,以潜江市东荆新区紫光大道跨越汉宜高速公路潜江互通为例,从路线设计、跨越方式、跨径组合、桥型结构等几个方面进行了研究,确定了跨越高速公路互通桥梁结构。

In order to solve the problem of urban arterial roads spanning expressways, this paper studies and determines the structure of interchange bridge spanning expressway from several aspects of route design,spanning mode, span combination and bridge structure by taking Qianjiang Interchange for Ziguang Avenue spanning Wuhan-Yichang Expressway in Dongjing New District of Qianjiang City as an example.
