摘　　要：随着国内城市开发建设水平的不断提高,很多城市规划了CBD(中央商务区),以此作为城市社会经济发展的引擎。但是由于CBD开发强度高,交通需求旺盛,因此早晚交通拥挤等问题逐渐凸显出来。为此,很多城市规划了地下环路以弥补地面路网的不足。通过对CBD路网特征的研究和国内外案例的分析,结合路网容量理论,提出是否需要建设地下环路的计算模型,为规划建设地下环路提供定量分析的理论支撑和技术手段。With the continuous improvement of the urban development and construction in China,many cities have planned central business district CBD as the engine of urban social and economic development.Due to the high development intensity and strong traffic demand in CBD,the traffic congestion in the morning and evening have also been highlighted.Therefore,many cities have planned the underground ring roads to make up the deficiency of ground road network.Through the research on the characteristics of CBD road network and the analysis on the cases at home and abroad,combined with the road network capacity theory,the calculation model of whether to build the underground ring road is put forward,which provides the theoretical support and technical means for the quantitative analysis on the planning and construction of underground ring road.
