DYNAMIC AND STATIC FIELD TESTS ON A SMALL INSTRUMENTED PILE

A PROCEDURE IS NEEDED WHEREBY THE BEARING CAPACITY OF AN AXIALLY LOADED PILE CAN BE DETERMINED FOR ANY COMBINATION OF SOIL AND DRIVING CONDITIONS. THIS REPORT PRESENTS THE RESULTS OF A SERIES OF FIELD TESTS WHICH WERE CONDUCTED WITH A SMALL INSTRUMETED PILE, 2,5 INCHES IN DIAMETER BY 24 INCHES LONG, INSERTED 8 INCHES INTO THE SOIL. TESTS WERE MADE IN SEVERAL SOILS, RANGING FROM HIGHLY PLASTIC CLAYS TO SILTY SANDS. SKIN FRICTION AND POINT BEARING MEASUREMENTS WERE TAKEN TO DETERMINE SOIL DAMPING CONSTANTS, ELASTIC SOIL DEFORMATION OR QUAKE, AND DISTRIBUTION OF LOAD BETWEEN SKIN FRICTION AND POINT BEARING IN THE SOILS TESTED, IN ACCORDANCE WITH E.A.L. SMITH'S MATHEMATICAL EXPRESSION. TEST RESULTS IN COHESIVE FINE-GRAINED SOILS WERE REASONABLE. THEY WERE INCONCLUSIVE IN COARSER-GRAINED SOIL. ADDITIONAL TESTING WITH LONGER AND LARGER DIAMETER PILES IS RECOMMENDED. /BPR/
