Abstract

In this learned article the analysis of the volume stress-strain condition of the soils in the tunnel’s face in the cases of different repulses of support lining with applying of a finite-elements method is adduced. The graphic relations of stresses and displacements of the soils is developed and with respect to these relations the influence of the magnitude of repulse of support lining at the volume stress-strain condition of the soil massif is defined.
