广州南沙横沥岛尖地下环路工程总体方案设计

近年来,地下车库联络道(或称地下环路)频繁的出现在高强度开发区域的规划设计中,用以解决随着机动车保有量的不断增长而日益突出的交通问题。广州南沙新区明珠湾起步区(横沥岛尖)地下环路工程是服务岛内核心区到发交通,扩容区域路网容量,减少地面交通压力,提升地面环境品质的重要工程。综合考虑现状与规划条件、功能定位以及交通组织与运行等因素,对工程的建设标准、出入口方案、总体方案等进行综合分析与评估,并提出了合理的设计方案；为相关地下空间的道路交通设计提供了有益的参考。

Design of Overall Scheme for Underground Ring Road Project in Hengli Island, Nansha New District, Guangzhou

In recent years, the underground garage link frequently appears in the planning and design of high-intensity development area to solve the traffic problem which is becoming more and more prominent with the continuous growth of motor vehicle. The underground ring road project at the starting area of Mingzhu Bay (Hengli Island) in Nansha New District of Guangzhou is an important project to serve the traffic in the core area of the Hengli Island, expand the capacity of the regional road network, reduce the pressure of ground traffic and improve the quality of the ground environment. By considering the current situation and planning conditions, functional positioning, traffic organization and other factors, the construction standard of the project, entrance and exit scheme, and the overall scheme are comprehensively analyzed and evaluated. And a reasonable design scheme is put forward, which provides the reference for road traffic design of the relative underground space.
