PILE DRIVING ANALYSIS-SIMULATION OF HAMMERS, CUSHIONS, PILES, AND SOIL

RESEARCH WAS CONDUCTED ON THE APPLICATION OF THE WAVE EQUATION TO THE ANALYSIS OF PILES FOR STRUCTURAL ADEQUACY DURING DRIVING AND LOAD-BEARING CAPACITY. CORRECT ASSUMPTIONS REGARDING THE DYNAMIC BEHAVIOR OF THE MATERIALS AND EQUIPMENT MUST BE MADE AND ALL SIGNIFICANT PARAMETERS INCLUDED IN THE ANALYSIS TO OBTAIN A CORRECT AND ACCURATE SOLUTION OF THE WAVE EQUATION FOR PILE-DRIVING ANALYSIS. AN EVALUATION IS PRESENTED OF THE RELATIVE SIGNIFICANCE OF THE FOLLOWING MATERIAL AND EQUIPMENT PARAMETERS THROUGH CORRELATIONS OF ANALYTICAL AND EXPERIMENTAL DATA: (1) DYNAMIC DAMPING OF IMPACT WAVES IN STEEL AND CONCRETE PILING, (2) DYNAMIC LOAD-DEFORMATION PROPERTIES OF CUSHIONING MATERIALS, (3) THE ENERGY OUTPUT OF VARIOUS PILE DRIVING HAMMERS, (4) THE EFFECT OF RAM ELASTICITY ON PILING BEHAVIOR, AND (5) THE INFLUENCE OF VARIOUS METHODS OF DESCRIBING SOIL BEHAVIOR. THE PRACTICAL RANGES AND SIGNIFICANCE OF EACH OF THE PARAMETERS WERE IDENTIFIED AND A FORMULA IS PRESENTED WHICH ADEQUATELY DEFINES THE ENERGY OUTPUT FOR ALL TYPES OF PILE-DRIVING HAMMERS (STEAM AND DIESEL). A PROGRAM OF RESEARCH IS RECOMMENDED FOR OPTIMIZING PILE-DRIVING HAMMER EFFICIENCIES FOR FASTER DRIVING AND REDUCED DRIVING STRESSES.
