摘　　要：通过兰州地铁2号线盾构隧道穿越建筑物施工过程的三维数值模拟,分析地铁隧道施工对地层扰动出现的上部建筑物沉降变形以及盾构隧道管片结构受力安全。研究结果对指导工程设计和施工具有十分重要的意义,也可为类似工程提供参考。Based on the 3 D numerical simulation of shield tunnel crossing the building in Lanzhou Metro Line 2,the paper analyzes the subsidence deformation of the superstructure caused by the stratum disturbance and the safety of shield tunnel tube structure.The research results are of great significance to guide engineering design and construction,and can also provide reference for similar projects.
