This paper describes a beadng capacity formula for steel pipe pile with four helical wings , The pile can be possessed high bearing capacitl , becausc gf being screwed in widl lateral soil displacemen 匸 . 21 vcrticanoadlng こ est 亀 1n which a new measurin8 syst fbr axial strain of the pile was devised , were performed to evaluate the bearing capacity of th。se piles in vahous 囲 ds . A convenient bearing capacity formula , which is considered as a sum of end bearing capacity ofthe pile tip and four wings, is proposed based on the t¢ st
