A simplified method for investigating the bending behavior of piles supporting embankments on soft ground

Frontiers of Structural and Civil Engineering Pages 1021-1032 doi: 10.1007/s11709-023-0952-3

Abstract: In recent years, concrete and reinforced concrete piles have been widely used to stabilize soft grounddeformation mechanism and Poulos’ solution for pile–soil interaction to investigate the bending behavior of pilesThe results reveal that there are three possible bending failure scenarios for such piles: at the interfaceIn addition, floating piles that are not embedded exhibit an overturning pattern of movement in the softground layer, and a potential failure is located in the upper part of these piles.
