摘　　要：在当前城市地下空间规划工作不断升级的背景下,有关地下车库、轨道交通等地下结构地加层施工问题日渐突出。论文以某轨道交通工程为例,从项目所在区域的地质情况分析入手,研究了既有地下空间暗挖加层施工技术在该轨道交通工程中的应用,并从安全、环境、料具管理3个方面总结了施工中的注意事项。Under the background of the continuous upgrading of urban underground space planning, the problems of the construction of underground structures such as underground garage and rail transit are becoming more and more prominent. Taking a certain rail transit project as an example, this paper studies the application of the existing underground space construction technology in the rail transit project from the analysis of the geological situation of the project area, and summarizes the matters needing attention in the construction from the aspects of safety,environment and material and tools management.
