| 摘要： | A time-dependent 3D finite element model of the super-diameter EPB shield tunneling in soft, water saturated soil is presented.The computed effective stress and excess pore pressures in the soil around tunnel and the predicted soil deformations are studied in detail.Parametric analysis is executed to investigate the effect of the segment assembling time and longer shield machine stops on the soil behavior in the vicinity of the tunnel. |
