Webb5 dec. 2006 · A closed-form analytical solution has been derived that accounts for the inter-relation between liner, ground, and pore pressures. Elastic response of the liner and ground, and plane strain conditions at any cross-section of the tunnel are assumed. WebbTwo schemes were proposed during testing: one scheme was without support and the second was with asymmetric support from highly pre-tightened constant resistance anchor cable. Digital speckle displacement analysis system and micro-ground-stress sensors were employed to measure the deformation and shear stress distribution of the tunnel.

WebbPrinciple.-The behavior of a tunnel support in the ground is a typical ground-structure interaction problem. A tunnel support under the influence of the in-situ ground stresses will contract and change its shape; these …
