Analytical Study of Soil Displacement Induced by Twin Shield Tunneling in Semi-Infinite Viscoelastic Ground

Figure 7

Different shear moduli, , cause a change in the settlement value at point (−10, 0, 10) with time under the action of the support pressures (a), shield shell frictions (b), grouting pressures (c), and total displacement over time (d).
