IN-SITU MEASUREMENTS OF FRICTION AND BEARING CORRELATED WITH INSTRUMENTED PILE TESTS

THE DEVICE WAS USED TO MEASURE SKIN FRICTION AND POINT BEARING DURING SOIL SAMPLING OPERATIONS. THE TEST PROCEDURE WAS ADAPTED FOR USE WITH A STANDARD CORE DRILLING RIG. THE SKIN FRICTION AND POINT BEARING MEASUREMENTS WERE COMPARED WITH VALUES OF SKIN FRICTION AND POINT BEARING OBTAINED FROM TWO FULL-SCALE INSTRUMENTED TEST PILES. ALL TESTS WERE CONDUCTED AT ONE TEST SITE IN A CLAY SOIL. TO CORRELATE IN-SITU MEASUREMENTS WITH THOSE FROM THE INSTRUMENTED PILES, IT WAS NECESSARY TO DEVELOP ADJUSTMENT FACTORS TO CORRECT FOR THE SIZE AND SHAPE EFFECTS. THE ADJUSTMENT FACTORS WERE CORRELATED WITH THE PLASTICITY INDEX OF THE SOIL. /AUTHOR/
