FEM – Tunnel

FEM – Tunnel is used to design and analyze tunnels. Tunnel is an extension module of the FEM program for analysis of geotechnical problems.

Try GEO5 software yourself.
For free, without analysis restrictions.

Main Features

The module contains the following capabilities:

  • Two options for modelling linings (Beam elements - 1D or standard 2D elements)
  • The option to create a geometrical model of the lining in a separate pre-processor using data in an external format (such as DXF).
  • The simple introduction of the lining into the soil/rock body - topology correction and mesh generation are fully automatic
  • Any number of construction stages
  • Loading of the lining geometry in DXF format
  • Use of a relaxation factor to model the 3D behavior of the body during excavation
  • The introduction of hinged bearing ends of the beam elements
  • Input of temperature loads
  • Consideration of soil swelling
  • Consideration of lining shrinkage
  • Analysis of a secondary lining either by changing the geometrical parameters (1D elements) or by changing the parameters of the original lining to allow the transfer of stresses (2D elements)
  • The introduction of monitoring points anywhere in the body
  • Graphical representation of the distribution of internal forces on active parts of the lining
  • The introduction of anchors fixed at their end points or along their length(s)
  • The introduction of anchors as a region of improved soil mass (anchored region)
