Description Tunnel is an extension to the GEO5 program FEM, applicable for the modelling of tunnels and underground excavations. Features include:
- Automatic mesh generation
- Automatic generation of boundary conditions
- Modeling of bar and beam elements (anchors, anchor bolts)
- Standard constitutive models of soils (Elastic, Mohr-Coulomb, Drucker-Prager, Cam-Clay)
- Input of geometry of layers and structures
- Automatic correction of input topology
- Built-in database of soils and rocks
- An arbitrary number of surcharges (strip, trapezoidal, concentrated loading)
- An arbitrary number of anchors, beams
- Presence of water modeled through ground water table or using pore pressure isolines
- Possibility of creating the geometrical model of tunnel lining in a separate pre-processor (possibility of loading and saving data in selected format)
- Introduction of lining into the soil/rock body (topology corrector and mesh generator is fully automatic)
- An arbitrary number of stages of construction
- Import of lining (DXF-format)
- Using relaxation factor to account for the 3D behavior of excavation
- Possibility to introduce hinges
- Loading due to temperature changes
- Possibility to consider swelling of soils
- Possibility to consider shrinkage of lining
- Introduction of monitoring points anywhere in the body
- Graphical representation of distribution of internal forces on active parts of lining
- Introduction of anchors fixed at either their end points or along their length
- Introduction of anchors as a region of improved soil mass (anchored region)
- Dimensioning of steel-reinforced concrete lining using interaction diagram
Cost 2000 Euro
