... methods and rock mass classification for definition of subsurface parameter. The mechanical parameter of the rock masses were the basic input for different finite element models in order to evaluate the interacting static system of foundation and structures. The insights gained from these efforts were...

...: "Are classification systems outdated?" (Schubert 2013). This issue is very relevant, especially for conditions of great depths or weak rock. We ascertained that contradictions of Rock Mass Classifications (RMC) are consequences of verisimilar hypotheses, used without any empirical evidence in order to compensate...
