Numerical Study of Excavation Face Active Instability in Upward Shield Tunneling

To study excavation face instability in upward shield tunneling, a 3D numerical model was established using ABAQUS software v2023 under different depth ratios (<i>C</i>/<i>D</i> = 1, 1.5, 2, 3, 4), with reference to the upward shield tunneling project of the Midosuji Utility...
