ABSTRACT: The most common way of installing a pile is driving it using a hammer. The pile hammer forces the pile into the ground by repeated application of impulsive force. The employed hammer should be able to drive the pile to the desired depth without causing excessive driving stresses. In this paper, the data of the three major projects which involved numerous cases of pile driving were gathered. Using the collected data and employing a wave equation analysis program, GRLWEAP, an equation which estimates the induced stresses in the piles during pile driving, is proposed. Comparison of the results of the proposed equation with GRLWEPA program and a previously developed empirical equation shows a good agreement between them.
RÉSUMÉ: La manière la plus commune d'installer une pile la conduit utilisant un marteau. Le marteau de pile force la pile dans le sol par application répétée de la force impulsive. Le marteau utilisé devrait pouvoir enfoncer le pieu à la profondeur désirée sans causer des efforts moteurs excessifs. En ce document, les données des trois projets principaux que de nombreux cas impliqués de l'entraînement de pile ont été recueillis. Utilisant les données rassemblées et utiliser un programme d'analyse d'équation d'ondes, on propose GRLWEAP, une équation qui estime les efforts induits dans les piles pendant la pile conduisant. La comparaison des résultats de l'équation proposée avec le programme de GRLWEPA et d'une équation empirique précédemment développée montre une bonne concordance entre elles. 1 INTRODUCTION
