This paper is an investigation of face stability on a small-scale tunnel model in a geotechnical centrifuge. By making use of symmetry, half of the tunnel cross section was considered. The support at ...
COMPRESSIVE FAILURE MECHANISM OF DFORMED CONCRETE TUNNEL LININGS DUE TO A VERTICALLY CONCENTRATED LOAD
ground pressure cracking compressive behavior parabolic compressive softening model
