立体复合跨江通道工程总体设计探索

Explore of the Overall Design of the Three-dimensional Composite River-crossing Corridor

为在经济发达、高度城镇化地区实现土地集约利用,通道走廊资源共享,立体复合通道成为一种新的建设思路,狮子洋通道项目立体集成了1条高速公路和3条地方主要道路,形成了国内最大规模兼顾长途过境和市区内部集散功能与一体的立体复合跨江公路通道。以位于粤港澳大湾区核心区狮子洋通道工程为例对立体复合跨江通道总体设计进行了有益地探索。

In order to realize intensive land use and corridor resource sharing in economically developed and highly urbanized areas,three-dimensional composite corridors have become a new construction idea,and the Shiziyang Link Project integrates one expressway and three local trunk roads,forming the first three-dimensional composite river-crossing highway corridor in China that takes into account the functions of both long-distance transit and inner-city distribution.In this paper,the overall design of the three-dimensional composite cross-river corridor is explored relying on the Shiziyang Link Project which is located in the core area of Guangdong,Hong Kong and Macao Greater Bay Area.
