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.

A braced excavation is constructed in saturated ground. The construction stages, dewatering, excavation and braced support construction are simulated with FLAC. The purpose is to evaluate the deformation of the ground adjacent to the excavation and the performance of the wall and strut support. Three different material constitutive models are used to represent the soil behavior: Mohr-Coulomb, Cysoil, and PH models. The deformational response produced by these three models are compared.
