摘　　要：针对盾构隧道旁穿建筑物诱发的地表变形情况,采用岩土数值模拟软件FLAC3D对施工过程进行模拟分析。模拟结果表明:盾构施工引起的地表沉降值超出允许值。采取一系列控制措施后,经过实测验证,控制效果良好,能够有效地控制地表沉降,满足施工要求。In view of the surface deformation conditions induced by the shield tunnel driving alongside the existing housing,the geotechnical numerical simulation software FLAC3D is used to simulate the process of construction analysis. The simulation results show that the ground settlement values caused by shield construction exceeds the allowable values. After certain control technique measures are taken,the control effect is good. It can effectively control the surface subsidence and meet the construction requirements.
