MEASUREMENT OF STATIC AND DYNAMIC EXCESS STRESSES IN COLUMNS IN UNDERGROUND SHALLOW-DEPTH QUARRIES

MESURE DES SURCONTRAINTES STATIQUES ET DYNAMIQUES DANS LES PILIERS DES CARRIERES SOUTERRAINES PEU PROFONDES

ON TWO SITES IN THE DEPARTMENT OF THE NORD, PERPENDICULARLY TO SHALLOW CHALK QUARRIES, MEASUREMENTS WERE TAKEN OF STATIC AND DYNAMIC EXCESS STRESSES IMPOSED TO COLUMNS IN THE QUARRY BY VEHICLES OF GIVEN MASSES TRAVELLING AT GIVEN SPEEDS. THE SENSORS USED WERE STANDARD FLAT JACKS INSTALLED PERMANENTLY IN DIFFERENT COLUMNS. THE RECORDINGS OBTAINED GIVE A FIRST INDICATION OF THE INFLUENCE ON THE OVERSTRESSES OF FACTORS SUCH AS THE MASS AND SPEED OF THE VEHICLES, AND THE INITIAL LOAD ON THE COLUMNS. THEY ALSO ENABLE THE EXTENT AND SHAPE OF THE ZONE OF INFLUENCE OF A FIXED OR MOBILE SURCHARGE TO BE DEFINED. THESE EXPERIMENTAL RESULTS WERE COMPARED WITH THE RESULTS OBTAINED WITH CONVENTIONAL MODELS SUCH AS BOUSSINESQ OR DE HAYASHI MODELS.
