It is a certainty that a rock massif is a very complex environment, known only partially; in the laboratory we cannot produce all the details encountered in situ; therefore, most of the properties determined experimentally not fully express their real value that they have in rock massif. As theoretical basis we might consider theory of similitude initiated by Newton, in the sense of similarity that we can establish to the boundary between theory and experiment. Based on this and considering the applicable theorems...

In a practical context and with a tendency to generalize the dependence between monoaxial and triaxial compressive strength of rocks and qualitative characteristics and also properties of connection between the elements that form the skeleton of studied rocks were analyzed. This qualitative connection was highlighted by means of void index and apparent specific weight. The obtained correlation can be generalized to any type of rock, if it takes into account the amount of adsorbed and absorbed water, the direction ...
