摘要
城市地下道路发展日新月异,城市地下空间的开发需要更为集约高效的模式。以北京广渠路东延地下隧道方案选择为例,综合考虑道路功能发挥、周边地块需求、规范标准采用等因素,对隧道开挖的各种方案进行深入对比,探讨适合城市地下隧道的最优方案,认为明挖法更适合该工程的实际情况。隧道方案比选应充分利用地下空间,综合考量诸多因素,以求发挥城市地下道路服务城市的最大功能。
The urban underground road is developed quickly.The development of urban underground space needs a more intensive and efficient mode.Taking the selection of Beijing Guangqu Road East Extension Underground Tunnel Scheme as an example,this paper comprehensively considers the factors of road function exertion,surrounding land demand and standard adoption,further compares various schemes of tunnel excavation,and discusses the optimized scheme suitable for the urban underground tunnel.The result shows that the open excavation method is more suitable for the practical situation of this project.The selection and comparison of tunnel scheme should fully utilize the underground space and comprehensively consider many factors in order to play the maximum function of urban underground road service city.
