The authors performed statistical analysis of the data obtained from vertical loading test conducted on 14 kinds of 256 screw piles which were applied to The Building Center of Japan. The effects of the position of wing (pile shaft or pile tip), the shape of wing (helical plate or flat plate) and the shape of pile tip (closed end or opened end) upon the end bearing capacity and the frictional resistance were discussed. And further, the effects of the wing diameter and the wing/pile diameter ratio upon the bearing capacity factors of screw piles were clarified.
