THE BEHAVIOR OF AXIALLY LOADED END-BEARING PILES

THE BEHAVIOR OF A SINGLE AXIALLY LOADED END-BEARING PILE IN AN IDEAL ELASTIC SOIL IS ANALYZED AND SOLUTIONS ARE GIVEN FOR THE LOAD DISTRIBUTION WITHIN THE PILE, AND THE TOP AND TIP MOVEMENTS OF THE PILE FOR A WIDE RANGE OF CASES. IT IS SHOWN THAT THE BEHAVIOUR OF THE PILE IS LARGELY INFLUENCED BY THE LENGTH TO DIAMETER RATIO, THE STIFFNESS OF THE PILE RELATIVE TO THE SURROUNDING SOIL AND THE RELATIVE STIFFNESS OF THE BEARING STRATUM. IT IS FOUND THAT VERY SLENDER PILES ACT EFFECTIVELY AS FLOATING OR FRICTION PILES. THE INFLUENCE OF LOCAL YIELD BETWEEN THE PILE AND SOIL IS ALSO EXAMINED AND THE RESULTANT INCREASE IN TOP DISPLACEMENT IS FOUND TO BE LARGELY DEPENDENT ON THE DISTRIBUTION OF ADHESION ALONG THE PILE. COMPARISONS BETWEEN THE OBSERVED BEHAVIOUR OF END-BEARING PILES, OBTAINED FROM PUBLISHED MEASUREMENTS IN FIELD TESTS, AND THE THEORETICAL BEHAVIOUR SHOW GOOD AGREEMENT. /RRL/
