| TUNA is a fully automated
computer program developed for TUNnel Analysis. The program is written by the professional
engineer with more than 20 years of experience in tunnel analysis. TUNA employs a static, two-dimensional, linear elastic finite element
method. Pre- and post-processors are built-in so that only the physical geometries and
material properties associated with a proposed tunnel are required as input and graphical
otput can be obtained directly through dot matrix/laser printers or high resolution
plotters.

Features
- Liner-medium interaction
- English and Metric units
- Shallow and deep buried tunnels
- Multi-layered geological medium
- Circular, rectangular and horseshoe shape tunnels
- Plain concrete, steel plate, reinforced concrete and
composite integral liners
- Excavation and live loads
- Lined and unlined tunnels
Output Data

The following graphical output can be displayed on the
screen or printed through the hardcopy device:
- Tunnel deformed shape
- Principal stress in soil/rock
- Bending moment, thrust, extreme fiber stresses and strains in
the liner
- Stresses and strains in the reinforcing bars
