Group factors for pile-deflection estimation
WebJul 13, 2024 · The load-deflection response for the group piles is more flexible than the single pile , as per the research results by Papadopoulou and Comodromos , which states that the single pile has a greater lateral resistance than the group piles under the same load. In addition, the front row of the piles has the largest deflection, and it decreases ...
