INFLUENCE OF PRESSURE ON THE RHEOLOGICAL BEHAVIOUR OF ROCKS

INFLUENCE DE LA PRESSION SUR LE COMPORTEMENT RHEOLOGIQUE DES ROCHES.

IT IS SHOWN HOW, UNDER THE EFFECT OF INCREASING STRESSES AND TEMPERATURES, ROCKS GO FROM THE BRITTLE TO THE PLASTIC STATE: A DENSE LIMESTONE IS USED AS AN EXAMPLE FOR WHICH THREE STATES ARE DEFINED: BRITTLENESS, PSEUDO-PLASTICITY, PLASTICITY, THE SECOND BEING CHARACTERISED BY SLIDING AT PARTICLE JOINTS. THE LIMITS BETWEEN THESE STATES ARE CLEARLY DEFINED IN SPACE (MAIN STRESSES, TEMPERATURE).
