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: Intermediate Runs in Demo: No
FLAC simulates the four excavation stages and three construction steps within each stage for a multistage tunnel excavation and construction. The convergence-confinement method is used to simulate the effect of the tunnel advance. A ground reaction curve is calculated to relate the effect of the advancing tunnel face to reduction in internal pressure within the excavated region. Both rockbolt support and a shotcrete liner are installed at different stages of the tunnel advance.
