Abstract Based on the construction of Shanghai metro line No.6，the horizontal displacement，layered settlement，variation of pore water pressure caused by the construction of double-o-tube(DOT) shield in soft clay region are monitored continuously. Furthermore，the soil disturbance above sea-gulled segment is analyzed. The essential rules of soil disturbance induced by DOT shield excavation are summarized quantitatively and the characteristics of regional and time-dependent of DOT shield are brought forward.

Key words： tunneling engineering double-O-tube(DOT) shield soil disturbance pore water pressure environmental influence of soil engineering regional and time-dependent characteristics
