Design of tunnel lining of main line tunnels based on the evaluation of stress distribution patterns in tunnel lining

Comparison of results of calculations of the tangential stresses on the inner contour of tunnel lining and radial stresses on the outer contour is done. Stresses are found by solving the problem of interaction in geomechanical system «lining-ground massif» in 2D and 3D model (single layer tunnel lining and double layer tunnel lining). Area of correct application of 2D models are revealed.

Geomechanical substantiation of stability of the tunnel’s face which situated in the proterozoic clay’s

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.
