Tunnel* is the extension module of the FEM program.
In addition, the Tunnel 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 hinges
- 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)
* The module is not available separately. The FEM program is required. |
