The pile can be possessed high bearing capacity because of being screwed in with lateral soil displacement. 21 vertical loading tests, in which a new measuring system for axial strain of the pile was devised, were performed to evaluate the bearing capacity of these piles in various fields. A convenient bearing capacity formula, which is considered as a sum of end bearing capacity of the pile tip and four wings, is proposed based on the test results.}, pages = {57--60}, title = {多翼部を有する小径鋼管杭工法の開発}, year = {2000}, yomi = {ツチヤ, ツトム and ヨシダ, カツユキ and オオスギ, フミカズ} }
