Parametric Analysis and Control of Bedding-Inclined Asymmetric Stress in Double-Arch Tunnels: A 3DEC-Based Study on Jointed Rock Masses

Parametric Analysis and Control of Bedding-Inclined Asymmetric Stress in Double-Arch Tunnels: A 3DEC-Based Study on Jointed Rock Masses

Double-arch tunnels in inclined layered jointed rock masses face risks of lining cracking and collapse under bedding-inclined asymmetric stress (BIAS); however, related studies remain limited. Based on a case study of an expressway tunnel case in Zhejiang Province, a three-dimensional discrete eleme...
