DOI: 10.1139/cgj-2025-0386
Abstract: Large-diameter shield tunnelling in karst strata presents challenges in quantifying unbalanced loads and attitude control during cave-cutterhead interaction. This study develops a 3D explicit finite-element dynamic model of large-diameter cutterhead-rock interaction, validated through cutting torque… read more here.
