| 摘 要： | 地铁隧道施工扰动地层，地层应力释放产生相应变形，并且在不同条件下变形量表现出较大的差异。通过对深圳地铁Ⅰ期工程3A标国老区间隧道横断面地层深部位移的现场实测和回归分析，得出了深圳富水软弱地层中浅埋暗挖法施工地层运动的基本规律。由此提出控制地层大变形的技术措施，在Ⅰ期工程的后期施工中得到充分利用，取得了较好的指导施工效果。

| Abstract: | Constructing metro tunnel in shallow stratum destroys stratum structure, so stratum stress is freed and corresponding deformation is generated. By in-suit observation and regressive analysis together about deep stratum displacement of Shenzhen metro PhaseⅠProject Guomao-Laojie section tunnel cross-section, which caused by shallow tunnel construction method(STCM) construction in weak watery stratum of Shenzhen. basic movement regulations of stratum above tunnel, are achieved. Subsequently, corresponding technologic measures of how to control large deformation in stratum are advanced and fully applied to the late phase construction of Shenzhen metro PhaseⅠProject. Good effects are achieved in guiding tunnel construction. |
