ANALYSIS OF THE SETTLEMENT OF A SINGLE COMPRESSIBLE PILE

THE SETTLEMENT BEHAVIOR OF A SINGLE FLOATING PILE IS ANALYZED, TAKING INTO ACCOUNT THE COMPRESSIBILITY OF THE PILE MATERIAL ITSELF. INFLUENCE FACTORS ARE GIVEN FOR THE SETTLEMENT OF A PILE FOR A WIDE RANGE OF VALUES OF PILE STIFFNESS FACTOR "K" AND LENGTH/TO-DIAMETER RATIO "L/D". IT IS SHOWN THAT THE VALUE OF K MARKEDLY AFFECTS BOTH THE SETTLEMENT OF THE PILE AND THE DISTRIBUTION OF SHEAR STRESS ALONG THE PILE AND HAS A CONSIDERABLE INFLUENCE ON THE SHAPE OF THE LOAD-SETTLEMENT CURVE OF A PILE LOADED TO FAILURE IN A SATURATED CLAY UNDER UNDRAINED CONDITIONS. HOWEVER, THE RATIO OF THE IMMEDIATE SETTLEMENT TO THE TOTAL FINAL SETTLEMENT OF THE PILE IS ONLY SLIGHTLY AFFECTED BY K, WHILE THE REDUCTION IN SETTLEMENT DUE TO AN ENLARGED PILE BASE IS VIRTUALLY INDEPENDENT OF K. THE VALUE OF K AT WHICH THE BEHAVIOR OF A PILE IS IDENTICAL WITH THAT OF AN INCOMPRESSIBLE PILE (FOR WHICH K IS EQUAL TO INFINITY) INCREASES AS THE VALUE OF L/D INCREASES. COMPARISONS BETWEEN THE THEORETICAL BEHAVIOR OF A PILE AND THAT REPORTED FROM FIELD MEASUREMENTS OF PILES IN CLAY, SHOW ENCOURAGING AGREEMENT. /RRL/AUTHOR/
