(2011): Centrifuge model test on the face stability of shallow tunnel
ACTA GEOTECH. 2011; 6(2): 105-117. FullText FullText_BOKU

Abstract:
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 excavation face was provided by a piston, which was adjusted during flight. Some aspects on the collapse at tunnel face are investigated for different overburden pressures: failure mechanism, surface settlement, stress acting at tunnel face, and the required face support counteracting the earth pressure. Ground deformation was observed through a transparent wall and measured by digital image correlation. The results from centrifuge model tests were compared with theoretical models.
