Tunnel Design Tools

Design

Desk top studies and computer aided analysis and calculation for design of underground structures

Slopes

Investigation of stress concentration at the root angle of a road cutting into a slope, taking into consideration the natural strata of the slope.

Shells
A three dimensional FEM shell programme used to analyse ground load applied to the inner lining of an underground junction.

FEM
FEM calculation of the possible track deformation caused by settlement whan excavating a tunnel through a railway embankment. (see Geotechnics and Ground Control)

Frames
Specification of the tunnel lining performance by determination of the section forces acting in the lining.
