摘要
随着城市建设的发展,大量现有穿山隧道已不能满足交通出行的需要,修建复线隧道是缓解现状隧道交通压力的重要方式之一。针对如何修建复线隧道,并对相应的立交节点进行改造,以便接入城市核心区路网,以重庆市大学城复线隧道和红槽房立交为例,分析讨论城市复线隧道与片区路网的衔接,相关立交节点改造与周边道路、既有构筑物的关系,为类似工程的设计提供参考。
With the development of urban construction, a large number of existing tunnels fail to meet the demand of transportation. The construction of double-line tunnel is one of the important modes to reduce the traffic pressure of the present tunnel. Aiming at how to construct the double-line tunnel, the corresponding nodes of interchanges are reconstructed in order to link to the road network of urban core area. Taking the double-line tunnel in Chongqing University City and Hongcaofang Interchange as the examples, this paper analyzes and discusses the connection of urban double-line tunnel with the area road network, and the relationship between the reconstruction of relevant interchange nodes and the surrounding road and existing structures, which can be referred for the design of the similar projects.
