WAVE EQUATION ANALYSIS OF PILES INSTALLED WITH DIESEL HAMMERS. INTERIM REPORT

A study has been conducted to evaluate Case-Goble soil damping constants (J sub c) used in the pile driving wave equation procedure for computing static bearing capacity. Open-end diesel hammers were used in this study. Static bearing capacities were calculated from dynamic measurements of strain and acceleration during pile driving on ten projects. Full-scale static load tests were performed to verify the static bearing capacities. A pile capacity failure criterion was defined. The results were used to develop a correlation between J sub c and standard penetration test (SPT) values measured for silts and sands at the pile tip.
