DYANMIC PILE STUDIES IN OHIO

THIS ADVANCED TECHNIQUE FOR PREDICTING THE LOAD CARRYING CAPACITY OF PILES MAKES USE OF DYNAMIC MEASUREMENTS TAKEN DURING THE PILE DRIVING OPERATION. WITH THE AID OF SPECIALLY DESIGNED PILE ATTACHMENTS AND A PORTABLE SPECIAL PURPOSE COMPUTER, PREDICTIONS OF STATIC BEARING CAPACITY ARE PRODUCED ALMOST INSTANTANEOUSLY. THE APPLICATION OF A SIMPLIFIED WAVE ANALYSIS AND THE COMPUTATION OF THEORETICAL SOIL RESISTANCE USING A GIVEN EQUATION IS DESCRIBED. RESULTS DERIVED FROM ELASTIC WAVE THEORY WERE USED TO VERIFY THE AVERAGING PROCEDURE AND FURTHER REFINE THE PREDICTION METHOD. THE USE OF A TRANSDUCER TO MAKE FORCE MEASUREMENTS IS DESCRIBED. LIMITATIONS TO THE USE OF THIS DYNAMIC METHOD AT ITS PRESENT STATE OF DEVELOPMENT ARE DISCUSSED. IT IS CONCLUDED THAT THE PROSPECT OF USING DYNAMIC TEST EQUIPMENT UNDER ROUTINE TEST CONDITIONS IS GOOD.
