摘要
济南市顺河高架南延长线玉函路地下道路地处城市核心区,是济南市快速路路网体系中的重要组成部分。在对玉函路地下道路的总体设计介绍中,首先阐述了工程复杂的设计条件,然后对项目总体平面线位方案、地下道路断面及施工工艺进行了多方案分析比选,对地下道路南北洞口节点方案及地下道路附属工程解决方案进行了详细介绍。结论为:地下道路采用箱涵+双连拱+超小净距隧道组合布设的结构形式,在玉函路下方穿越;设计、施工一体化,采用明挖+暗挖组合施工工艺,有效克服了施工交通组织困难、地质条件复杂、地下管网密集等诸多技术难题。
The underground road of Yuhan Road in Shunhe Elevated South Extension Line in Jinan is located in the urban core,and is an important component in the expressway network system of Jinan.In the overall design of the underground road of Yuhna Road,the design conditions of the engineering complexity are firstly expounded.And then the overall plane alignment scheme of the project,and many schemes of underground road section and construction technologies are analyzed and compared.The node schemes for south and north openings of the underground road,and the auxiliary engineering solutions of the underground road are introduced in detail.The conclusion shows that the combined layout structure form of box culvert+double connecting arch+ultra-small clear distance tunnel is adopted for the underground road,and crosses under Yuhan Road.The design and construction are integrated,and the combined construction technology of trench excavation+trenchless excavation is adopted,which effectively overcome many technical difficulties of hard traffic organization,complex geological conditions and dense underground pipeline networks during the construction.
