5. Numerical modeling in rock mechanics

Examples of rock slope stability calculations and tunnel section dimensioning have shown that the methods used in these calculations at the scale of a rock mass require the consideration of a number of simplifying assumptions, which are sometimes very limiting. Numerical modelling is the approach that best takes into account the complexity of the reality of the material, whatever the scale involved, and of the structure or project being studied.

5.1 The contribution of numerical modeling to rock mechanics projects

In terms of physical phenomena, numerical modelling enables the behaviour of rock, discontinuities and rock mass to be finely modelled, depending on the application under consideration. They take into account a far greater range of physical phenomena...
