Experimental Study on Characteristics of Pile-Soil Interaction in Screw Piles
Buildings, 2022 A screw pile is a special-shaped pile with several advantages, including good bearing capacity, economy, and rapid construction. The calculation of the screw piles’ ultimate bearing capacity in the individual bearing failure state remains controversial.
