SETTLEMENT OF SINGLE COMPRESSIBLE PILE

THE SETTLEMENT BEHAVIOR OF A SINGLE COMPRESSIBLE FLOATING PILE IS ANALYZED AND INFLUENCE FACTORS ARE PRESENTED FOR THE SETTLEMENT FOR A WIDE RANGE OF VALUES OF LENGTH-TO-DIAMETER RATIO L/D AND PILE STIFFNESS FACTOR K, A MEASURE OF THE RELATIVE COMPRESSIBILITY OF THE PILE AND, FOR A SOLID PILE, THE RATIO OF THE YOUNG'S MODULI OF THE PILE AND THE SOIL. THE VALUE OF K MARKEDLY AFFECTS THE SETTLEMENT AND THE SHEAR STRESS DISTRIBUTION ALONG THE PILE AND HAS A CONSIDERABLE INFLUENCE ON THE LOAD-SETTLEMENT BEHAVIOR OF A PILE LOADED TO FAILURE IN A SATURATED CLAY UNDER UNDRAINED CONDITIONS. HOWEVER, THE RATIO OF THE IMMEDIATE TO THE TOTAL FINAL SETTLEMENT IS ONLY SLIGHTLY AFFECTED BY K WHILE THE SETTLEMENT REDUCTION DUE TO AN ENLARGED PILE BASE IS ALMOST INDEPENDENT OF K. THE VALUE OF K AT WHICH THE PILE BEHAVES AS AN INCOMPRESSIBLE PILE (FOR WHICH K = INFINITY) INCREASES AS L/D INCREASES. COMPARISIONS BETWEEN THE THEORETICAL BEHAVIOR OF A PILE AND THAT REPORTED FROM FIELD MEASUREMENTS OF PILES IN CLAY SHOW ENCOURAGING AGREEMENT. /ASCE/
