GEOSTRUCTURAL ANALYSIS TUNNEL
GeoStructural Analysis Tunnel is an extension to GeoStructural Analysis FEM that provides a finite element method modeling tool to analyze and design tunnel construction. Models of tunnels, anchored rock cuts, and slopes with anchorage elements provide expanded capabilities for analyses. Using GeoStructural Analysis Tunnel enables creation of thorough and sophisticated models of underground structures and excavations for better, safer design..
Key Features
- Model tunnel lining using beam elements
- Import data from formats such as DXF to create geometrical lining models
- Easily introduce the tunnel lining into the soil/rock body
- Fully automatic mesh generation and topology correction when tunnel lining is introduced into the model
- Analyze tunnel construction in stages
- Model 3D behavior by including relaxation factors (modeling of sequentional tunneling)
- Model hinges in the tunnel lining
- Determine influence of thermal loading on tunnel performance
- Determine effect of soil swelling and lining shrinkage on tunnel performance
- Generate graphical representations of the internal force distributions acting on the tunnel lining
- Analyze secondary linings through stress transfer in 2D elements by changing the parameters for either the 1D geometry elements or for the original lining
- Introduce monitoring points at any point in the body
- Introduce fixed anchors at specified end points or at any point along the length(s)
- Introduce anchored regions of improved soil mass
