INTERACTION BETWEEN WATER FLOW AND THE MECHANICAL BEHAVIOUR OF SOIL OR ROCK MASSES

INTERREACTION ENTRE LES ECOULEMENTS D'EAU ET LE COMPORTEMENT MECANIQUE DES MASSIFS DE SOLS OU DE ROCHES

THE AUTHORS STUDY THE LAWS GOVERNING THE MECHANICAL EFFECTS DUE TO WATER FLOW IN MASSES AND DEFINE THE MEANS BY WHICH THESE EFFECTS CAN BE TAKEN INTO ACCOUNT IN CALCULATIONS, BY USING, FOR EXAMPLE, MATHEMATICAL MODELS FOR THE SIMULATION OF THE MECHANICAL BEHAVIOUR OF MASSES (FINITE ELEMENT METHOD). THE NUMERICAL APPROACH USES BOTH HYDRAULIC AND MECHANICAL MODELS. THIS COUPLING CAN BE OBTAINED FOR A FIXED GEOMETRY MASS (I.E. CONSTANT PERMEABILITY) OR FOR A VARIABLE GEOMETRY MASS WITH PERMEABILITY AS A FUNCTION OF THE STRAIN STATE. IN THIS CASE THE SOLUTION IS OBTAINED BY SUCCESSIVE HYDRAULIC AND MECHANICAL SIMULATION.
