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
The stability of a slope subjected to rainfall events of increasing intensity and decreasing duration is analyzed with FLAC. The apparent cohesion provided by capillary forces in unsaturated soil is simulated using the two-phase fluid flow logic. As soil saturation increases, soil cohesion can decrease and result in slope collapse.
