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.
