  • Few theoretical methods and experimental data exist for the analysis of tunnel‐face stability in cohesionless soils. The present paper addresses a series of practical questions by using centrifugal‐model tests. The values of limit internal‐support pressures are given for various conditions (density of the sand, position of the tunnel with respect to the ground surface). These values are shown to be low as predicted by the latest limit‐calculation models and collapse is shown to be sudden. The… CONTINUE READING
