This training is an introduction to continuous modeling with FLAC2D and FLAC3D. At the end of the course, participants will master the graphical interface, documentation and the main modeling steps. Concepts are illustrated using a tunnel excavation example, from building the model geometry to results analysis. This introductory course provides the foundation for more advanced use of the software, which can be covered in more specific training modules.
Version Notes:FLAC 8.0
Level: Advanced Runs in Demo: No
A circular lined tunnel is constructed in saturated ground. The ground is dewatered during construction. The tunnel is supported by a temporary shotcrete liner, which is installed while the tunnel excavation is advanced. A final cast-in-place concrete liner is then constructed. The water level is then returned to the original level. The analysis determines the forces and moments that develop in the concrete liner when the water level is returned to the original level, and when the temporary shotcrete liner loses strength.
