摘　　要：基于青岛某地铁区间施工过程中穿越某大厦的实际问题,采用Midas-GTS建立三维有限元模型进行模拟,研究隧道施工引起建筑物位移和内力变化问题。结果表明,隧道施工采用超前小导管注浆加固,建筑物变形得到控制,结构内力明显下降,可有效保护地表建筑物安全。based on a range of practical problems in the process of a subway construction crossing a building inQingdao, Midas-GTS was adopted to establish the three-dimensional finite element model to simulate, the influences oftunnel construction on building deformation and the change of internal force were studied. The results show that ,whenleading catheterwas adopted to grout and reinforce in the tunnel construction, the building deformation was controlled,the structure internal force decreased significantly, which effectively protected the safety of surface buildings.
