BEHAVIOR OF PILE GROUPS SUBJECT TO EXCAVATION-INDUCED SOIL MOVEMENT. Centrifuge model tests were conducted on free- and capped-head pile groups consisting of 2, 4, and 6 piles located adjacent to an unstrutted deep excavation in sand. It was found that when 2 free- or capped-head piles are arranged in a row parallel to the retaining wall
