PERFORMANCE OF PILE DRIVING HAMMERS

THE ACTION AND BEHAVIOR OF HAMMER-PILE SYSTEMS IS DISCUSSED USING RESULTS FROM BOTH THEORY AND MEASUREMENTS. THREE TYPES OF MODELS ARE USED TO DESCRIBE THE BEHAVIOR OF A HAMMER-PILE SYSTEM. ONE IS THE WAVE SOLUTION OF ST. VENANT FOR A PILE STRUCK BY A RIGID BODY. THE TWO OTHER MODELS USE A MASS AND A SPRING TO DESCRIBE THE EFFECTS OF BLOCKS AND CUSHIONS, RESPECTIVELY. THE INTERPRETATION OF MEASURED QUANTITIES USING SUCH MODELS ALLOWS CONCLUSIONS TO BE DRAWN REGARDING THE DRIVING ABILITY OF A HAMMER, SITUATIONS INVOLVING PILE DAMAGE, ENERGY LOSSES AND TRANSFER, AND CHARACTERISTICS OF CERTAIN MEASURED QUANTITIES. AS A RESULT, IT IS SHOWN THAT THE MICHIGAN RECORDS WERE MEANINGFUL WITHIN THE PARTICULAR MEASURING SYSTEM USED AND RECOMMENDATIONS ARE GIVEN FOR A TRANSDUCER DESIGN THAT ALLOWS THE MEASUREMENT OF MORE MEANINGFUL QUANTITIES. DIESEL HAMMER PERFORMANCE AND ENERGY OUTPUT IS ANALYZED AND IT IS SHOWN THAT THESE HAMMERS PERFORM ADEQUATELY. /AUTHOR/
