  Quantitative Analysis on the Minimum Support Load for Tunne lling

  Abstract: ABSTRACT: This paper addresses the problem of assessing the stability conditions of shallow excavations. A closed-form statically admissible solution, which allows an estimation of the support pressure where the cavity is at the verge of equilibrium, is presented. The solution has been derived with the assumption that the circular opening is excavated in ground modelled with the Mohr-Coulomb...
