DISCUSSION ON PILE TESTS: ARKANSAS RIVER PROJECT

THE AUTHORS ARE TO BE COMMENDED FOR: (1) PERFORMING FULL SCALE FIELD MEASUREMENTS OF STRAINS AND LOADS FOR DIFFERENT TYPES OF PILES (2) PRESENTING THEM TO THE PROFESSION IN PUBLISHED FORM; AND (3) GIVING A CLEAR IDEA OF THE SOIL CONDITIONS EXISTING AT THE SITES. THE PAPER IS A GREAT ASSET TO PRACTICING FOUNDATION ENGINEERS IN REGARD TO THE INSTRUMENTATION AND TECHNIQUES REPORTED BY THEM FOR CARRYING OUT COMPRESSION AND TENSION TESTS ON PILES. ALSO, THE DATA MAY BE USEFUL TO RESEARCH WORKERS STUDYING PILE FOUNDATION LOAD TRANSFER AND ULTIMATE BEARING CAPACITITY. FIGURES 11 AND 12 AND FIGURES 18 AND 19 SHOW THE AXIAL LOAD DISTRIBUTION WITH DEPTH FOR COMPRESSION AND TENSION PILES, RESPECTIVELY. A STUDY OF THESE FIGURES INDICATES THAT THE RATE OF DECREASE OF AXIAL LOAD WITH DEPTH IS GREATER FOR PILES IN COMPRESSION THAN FOR PILES IN TENSION. WHILE STUDYING MODEL PILE GROUPS EMBEDDED IN SANDY SOIL OF UNIFORMITY COEFFICIENT 1.1 UNDER VERTICAL AND LATERAL LOADS, THE WRITER HAD THE OPPORTUNITY TO STUDY SOME OF THE PILES IN THE GROUPS UNDER COMPRESSION AND TENSION AND THE AXIAL DISTRIBUTION OF LOAD ALONG THE DEPTH OF THE PILES. THE AXIAL LOAD ALONG THE DEPTH OF THE PILES WAS COMPUTED BY INITIALLY CALIBRATING THE PILES UNDER COMPRESSION AND TENSION LOADING. THE TREND IS SIMILAR TO THAT OF THE AUTHORS. THE MODE OF BEHAVIOR CAN BE ATTRIBUTED TO THE SOIL BECOMING LOOSE NEAR THE PILES UNDER TENSION AND DENSE NEAR THE PILES UNDER COMPRESSION. THE TRANSFER OF LOAD BECOMES, THEREFORE, MORE RAPID IN THE STIFFER SOIL. /AUTHOR/
