THE USE OF CENTRIFUGAL FORCE FOR THE PREPARATION OF SMALL-SCALE MODELS OF EARTH STRUCTURES. DESIGN AND USE OF A VACUUM TABLE FOR THE CONSTRUCTION OF THE MODELS

CENTRIFUGATION DE MODELES REDUITS D'OUVRAGES EN TERRE, CONCEPTION ET UTILISATION D'UNE TABLE A VIDE POUR LA CONSTRUCTION DES MODELES

THE AUTHORS DESCRIBE THE EQUIPMENT DESIGNED FOR THE TRANSPORT AND INSTALLATION IN A CONTAINER OF A THIN LARGE SLICE OF SOIL USED IN THE CONSTRUCTION OF THE MODEL. THIS DEVICE: THE VACUUM TABLE, HAS ALREADY BEEN USED BY PROFESSOR ROWE. THE PRINCIPLE OF THE DEVICE IS AS FOLLOWS: A SLICE OF SOIL OF A GIVEN CROSS SECTION: S, HEIGHT: H, SPECIFIC WEIGHT: GAMMA, CUT IN A SAMPLE: D OF REDUCED PRESSURE: DELTA PO COMPARED TO THE ATMOSPHERIC PRESSURE: PA, IS PLACED ON THE UPPER SURFACE. THE VACUUM THEORETICALLY NECESSARY AND SUFFICIENT TO RAISE THE SLICE OF SOIL IS SUCH THAT DELTA PO IS GREATER THAN GAMMA H. THE AUTHORS DESCRIBE THE VACUUM TABLE BUILT: VACUUM CHAMBER, PIPES AND LINK WITH THE VACUUM SOURCE, VACUUM SOURCE, LIFTING SYSTEM. DETAILS ARE GIVEN OF TESTS CARRIED OUT IN THE LABORATORY, AND OF THE CUTTING AND PLACING OF THE MODEL IN THE CONTAINER DURING A TEST WITH CENTRIFUGAL FORCE.
