Analytical and Numerical Study of the Support Pressure for the Stability of Shallow Underground Openings
Abstract: This paper describes the problem of assessing the stability conditions of shallow excavation of circular shape, namely circular sections of long cylindrical tunnels, in ground as it is modelled with a Mohr-Coulomb material. Firstly, the problem results in a closed-form statically admissible solution for cavities under the horizontal ground surface that allows an estimation of minimum support...

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...
