INVESTIGATIONS OF BEARING CAPACITY OF PILES IN SAND

THIS REPORT PRESENTS A SUMMARY OF THE SECOND PHASE OF A LARGE-SCALE LABORATORY-FIELD INVESTIGATION OF THE BEARING CAPACITY AND SETTLEMENT OF PILES AND PILE GROUPS IN SAND. IN THIS PHASE, 4-INCH DIAMETER STEEL PILES WERE DRIVEN INTO LABORATORY MODELS OF HOMOGENEOUS MASSES OF SAND OF DIFFERENT RELATIVE DENSITIES AND TESTED SUCCESSIVELY AT DIFFERENT DEPTHS UP TO 120 INCHES. THE PILES WERE CONSTRUCTED ON THE PRINCIPLE OF DEEP CONE PENETROMETERS, WITH SPECIAL LOADING CELLS FOR SEPARATE REGISTRATION OF POINT AND SKIN LOADS. DISPLACEMENTS OF THE PILES AND OF THE SAND WERE ALSO RECORDED. THE EXPERIMENTS WERE REPEATED ON A FIELD SITE IN A REASONABLY HOMOGENEOUS MASS OF NATURAL, MOIST LOOSE SAND, VERY SIMILAR TO THE SAND USED IN THE LABORATORY TESTS. THE INVESTIGATION SHOWED, AS IN THE CASE OF BURIED DEEP FOUNDATIONS, THAT THE UNIT POINT AND SKIN RESISTANCES OF DRIVEN PILES DO NOT INCREASE LINEARLY WITH DEPTH. AT GREAT DEPTHS, BOTH RESISTANCES REACH ASYMPOTICALLY CONSTANT FINAL VALUES, WHICH APPEAR TO BE FUNCTIONS OF THE RELATIVE DENSITY OF THE SAND. /AUTHOR/
