DETERMINATION OF PILE BEARING CAPACITIES

THE BASIC OBJECTIVE WAS TO DETERMINE A MORE ACCURATE, RAPID AND SIMPLE METHOD TO DETERMINE PILE BEARING CAPACITIES OTHER THAN THE "STANDARD" DYNAMIC FORMULAS. SEVERAL MINOR OBJECTIVES WERE ALSO STUDIED. DURING THE INVESTIGATION PILES OF VARIOUS TYPES WERE DRIVEN WITH SEVERAL TYPES OF HAMMERS. PILING WAS LOAD TESTED AT SEVEN SITES LOCATED IN VARIOUS SOIL TYPES AND FORMATIONS. ELECTRONIC INSTRUMENTATION AFFORDED AN EXCELLENT RECORD OF DYNAMIC FORCES OCCURRING WITHIN THE COMPLEX SOIL-PILE HAMMER SYSTEM. ALSO A PENETRATION-TIME RECORD WAS COLLECTED BY ELECTRONIC MEANS. ALL DRIVEN PILING WERE LOADED TO FAILURE OR JACK LIMIT AFTER DRIVING. FOUR TEST SITES CONTAINED CAST-IN-PLACE CONCRETE PILING WHICH WERE ALSO LOAD TESTED TO FAILURE. /AUTHOR/
