I have developed a screw steel pipe pile with toe wing having an inner wing. In this paper, I did a load test in ground of cohesive soil and sandy soil. As a result, for ultimate bearing capacity of the toe wing, I found the following. By applying the bearing capacity formula of sandy soil, bearing capacity factor can be set to 250. Further, by applying the same formula, pile toe effective area may be 0.5 times of the inner blade and blade toes. Pile head settlement amount was found to be below allowable settlement in the continuous footing.
