DETERMINATION OF THE MAXIMUM DENSITY OF COHESIONLESS SOILS

THE RESULTS OF VIBRATION TESTS ON AN AIR-DRY DUNE SAND ARE REPORTED. TESTS WERE CONDUCTED ON A VIBRATING-TABLE APPARATUS WHICH ALLOWED INDEPENDENT VARIATION OF AMPLITUDE, FREQUENCY AND SURCHARGE. THE COMPACTED SURCHARGE LED TO A DECREASE IN THE FINAL COMPACTED DENSITY, OTHER CONDITIONS BEING CONSTANT. AT NO SURCHARGE, THE COMPACTED DENSITY INCREASED TO A MAXIMUM WITH INCREASING PEAK ACCELERATION OF VIBRATION, OBTAINED WITH A VIBRATING-TABLE APPARATUS, THE FREQUENCY AND AMPLITUDE OF VIBRATION CANNOT BE SELECTED ARBITRARILY. SINCE THE "OPTIMAL" ACCELERATION VARIES WITH GRAIN-SIZE DISTRIBUTION, THE RELATIONSHIP BETWEEN DENSITY AND PEAK ACCELERATION MUST BE DERIVED FOR EACH SOIL TESTED IN ORDER TO ESTABLISH THE MAXIMUM DENSITY. /RRL/AUTHOR/
