摘　　要：目前,地下道路的建设已成为解决城市交通拥堵的重要手段,而科学、合理地进行地下道路横断面设计是控制建设规模和工程投资、促进地下道路快速发展的关键。文章介绍了地下道路横断面组成,分析了西方发达国家地下道路横断面的设计标准。阐述了我国城市地下道路的功能定位和分类,并结合我国实际,提出了单车道和多车道两种典型的地下道路横断面布置型式,对地下道路机动车车道宽度的确定、横坡设计、紧急停车带设置的方法等问题进行了有益的探讨,以期对我国地下道路的建设和发展起到一定的参考和借鉴作用。At presently, the construction of urban tunnel have become a crucial means for solving city traffic congestion, scientific and rational design for urban tunnel cross - section is the key which can control construction scale and make urban tunnel develop rapidly. After introducing the component elements of urban tunnel cross-section,the design criterion of every component elements of urban tunnel cross-section are analyzed comprehensively on in western developed country in the presented paper. The function orientation and classification of urban tunnel are expounded in our country. Integrating with the actual traffic condition of urban tunnel, the presented paper puts forward two typical layout styles of urban tunnel cross-section such as single lane cross-section and multi - lane cresssection, and puts up instructive discussion on the lane width of urban tunnel, design of cress-fall, layout style of emergency lav-bys, which will play referenced role on planning, design, construction for urban tunnel in our country.
