DETERMINING PILE BEARING CAPACITY BY SOME MEANS OTHER THAN THE ENGINEERING NEWS FORMULA. FINAL COMPREHENSIVE REPORT

A review of the practice used in monitoring pile driving activities within the Louisiana Department of Transportation and Development (LADOTD) and elsewhere is reported. The Engineering News Record formula is currently the most commonly reported method used by departments of transportation in the evaluation of pile driving. The performance of several alternate dynamic formulas, the wave equation, and dynamic testing with the pile driving analyzer are evlauated in a comparative study of LADOTD test piles. Development of a comprehensive program that includes dynamic formulas but has the goal of greater reliance on the wave equation, from design through construction, is recommended. Microcomputer software was developed to facilitate field implementation of WEAP87, the Hiley and Engineering News Record formulas. In a test pile study, the pile driving analyzer was found to be reliable in predicting pile capacity, in monitoring the structural integrity of the pile during driving, and in evaluating setup.
