Abstract

Recently, because of mega foundations and grand bridges, the foundations require significant bearing capacity. In this study, bearing capacity of high strength steel pipe pile with an extended head (HSP) is calculated on the basis of domestic criteria and Japanese criteria. And bearing capacity of HSP is investigated based on 3 field tests. In comparison with the results of analysis and tests, it is shown that the field test results are bigger than analysis results. Therefore, it is proposed to estimate bearing capacity of HSP.
