When heavy structures on weak soil are built a deep foundation must normally be used. Piles are usually the best economical and technical solution for this type of foundation. This article presents the results of a vertical loading test on a closed-end steel pipe pile with an outer diameter of 812.8 mm and length of 45.8 m driven by a 61 kN ram weight diesel hammer through the normally consolidated recent littoral silty-clayey sediments into a bearing sandy-gravely soils. The pile was tested twice, reaching two different depths. The main emphasis of the article is to compare the ultimate bearing capacity obtained by a maintained loading test and by dynamic testing. Dynamic testing was performed by measuring strain and acceleration near the head of the pile as a function of a time and data processing using wave equation analysis.
