MODEL TESTS ON FLOW THROUGH FISSURED MEDIA /IN GERMAN/

MECHANICAL STRESSES CAUSED BY FLOW OF WATER IN ROCKS AND THEIR INFLUENCE ON THE STABILITY OF THE ROCK MASS ARE STUDIED. THE WATER FOLLOWS THE CRACKS IN THE ROCK AND THE HYDRAULIC BEHAVIOR OF THE LATTER BECOMES ANISOTROPIC. THE DISTRIBUTION OF THE HYDRAULIC POTENTIAL AND THAT OF FLOW AND DISCHARGE PRESSURES ARE CLOSELY LINKED TO THE DISTRIBUTION GEOMETRY OF THE SEPARATION SURFACES (FAULTS, JOINTS, CRACKS, FRACTURES). A REVIEW IS PRESENTED OF THE RESEARCH ON THE HYDRAULICS OF CRACKED MEDIA AND TWO-DIMENSIONAL METHODS OF DETERMINING HYDRAULIC POTENTIAL DISTRIBUTION IN A FISSURED MASS ARE OUTLINED. RESULTS OF THE THREE-DIMENSIONAL PROBLEM OF FLOW STRESSES ARE GIVEN. AN EXAMPLE OF FLOW PROBLEM IN THE VICINITY OF A TUNNEL BUILT IN A FISSURED ROCK MASS ILLUSTRATES THE THEORETICAL STUDY. THEORETICAL AND EXPERIMENTAL RESULTS RELATING TO THE HYDRAULIC POTENTIAL, RATE OF FLOW AND FLOW STRESS DISTRIBUTION ARE COMPARED. MODEL MEASUREMENTS ARE IN AGREEMENT WITH THEORETICAL RESULTS. /LCPC/RRL/
