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 bounding surface plasticity model recently updated based on cyclic simple shear tests of UC Berkeley (Wu, 2003). An option to apply residual strength Sr is available for the user. The Sr can be applied at a user selected pore pressure ratio Ru.
