VIBRATORY DRIVING IN DIFFERENT TYPES OF SOIL

TO REDUCE THE DISCOMFORT TO PEOPLE AND EFFECTS ON BUILDINGS, COMPARATIVE STUDIES WERE CONDUCTED OF VIBRATORY DRIVING. TESTS WERE CARRIED OUT IN GRAVELLY SAND OF AVERAGE COMPACTION, IN A HIGHLY COMPACTED GRAVELLY SAND, AND IN A FINE-GRAINED CLAY VARYING IN DEGREE OF COMPACTION. THE PENETRATION OF THE DRIVEN SECTIONS WAS REPRESENTED BY A TIME DRIVING CHART. THE INFLUENCE OF DRIVING FREQUENCY WAS ALSO STUDIED. THE NOISE EMITTED WAS MEASURED FOR EACH TYPE OF APPARATUS USED. AN INVESTIGATION WAS MADE INTO THE DIFFERENCE BETWEEN MEASUREMENTS CARRIED OUT WITH PRECISION APPARATUS FOR MEASURING USUAL NOISE LEVELS AND MEASUREMENTS OBTAINED BY MEANS OF A PHYSICAL MEASUREMENT METHOD WHICH TAKES ACCOUNT OF SHORT-TERM IMPULSE NOISES. VARIOUS TECHNIQUES OF DAMPING NOISES DURING DRIVING WERE TRIED OUT. VIBRATIONS CAUSED BY THE APPARATUS AND THEIR EFFECTS WERE MEASURED AND EVALUATED. /TRRL/
