SAND-HYDRAULIC FILL IN ENCLOSED TEST PITS. MECHANICAL CHARACTERISTICS

THIS ARTICLE REPRODUCES THE TEXT OF A REPORT PRESENTED AT A ONE DAY CONFERENCE ON MARINE STRUCTURES HELD AT THE SAINT-BRIEUC LABORATORY, 9TH DECEMBER, 1975. DETAILS ARE GIVEN OF THE MAIN MECHANICAL CHARACTERISTICS (DENSITY, PRESSIOMETER, PENETROMETER) MEASURED IN ENCLOSED TEST-PITS HYDRAULICALLY FILLED WITH MARINE SAND. THE AUTHOR STUDIES THE POSSIBILITIES OF ESTABLISHING SHALLOW FOUNDATIONS WITHOUT ARTIFICIALLY IMPROVING THE MECHANICAL PERFORMANCE OF THE SAND AFTER A FEW MONTHS OF STABILIZATION. A METHOD IS PROPOSED FOR THE RAPID EVALUATION OF THE SETTLEMENT OF THE SAND UNDER ITS OWN WEIGHT.
