摘　　要：以某超高层建筑深基坑施工过程中地下室加层为例,详细阐述了后续支护加固方案和施工顺序,并采用有限元软件分析了地下室加层结构对周边地铁结构及设施的位移和受力影响,通过分析和实测数据对比,得出了基坑施工不危及紧邻地铁站及其附属结构安全的结论。This article takes the construction process of adding floors to the basement of a super high-rise building deep foundation pit as an example,and elaborates on the subsequent support and reinforcement plan and construction sequence.Finite element software is used to analyze the displacement and stress effects of the basement adding floor structure on the surrounding subway structure and facilities.Through analysis and comparison with measured data,the conclusion is drawn that the construction of the foundation pit does not endanger the safety of the adjacent subway station and its ancillary structures.

关 键 词：深基坑 加层 支护 模拟 安全
