摘要：本文依据上海市地铁15号线某区间岩土勘察所获得的地层资料，针对地铁盾构施工引起的地表沉降问题，采用FLAC3D建立了地层三维模型并赋予相应的地层参数，对该区间盾构隧道施工引起的地面沉降进行了数值模拟分析，对地铁盾构施工具有一定的指导与参考价值。
Abstract: Based on the stratum data obtained from the geotechnical investigation of a section of Shanghai Metro Line 15, aiming at the surface settlement caused by subway shield construction, this paper establishes a three-dimensional stratum model with FLAC3D and gives corresponding stratum parameters, and makes a numerical simulation analysis on the ground settlement caused by shield tunnel construction in this section, which has certain guidance and reference value for subway shield construction.
