| Abstract [eng] |
In the theoretical part a literature review on driven piles is carried out. The different materials and shapes of poles and their differences from other types of poles are reviewed. It discusses piles embedded in different types of soils (sand and clay and subsoil). Methodologies for calculating the bearing capacity of driven piles are examined. In the methodological part, the ultimate bearing capacity of the pile surface is calculated empirically from soil probing data. The method is described in LST EN 1997-1:2003. In the investigative part, the dependence of the bearing capacity of the driven pile on the soil type, the compressive strength and lateral friction properties of the soil, the diameter of the pile and the embedment depth of the pile is studied. The study showed that clay soils have the highest overall bearing capacity and sandy soils the lowest. The bearing capacity of a pile in clay soil is up to 2,6 times higher than in sandy soil when the pile is embedded at a depth of 9 m. The bearing capacity of the pile was found to increase with increasing pile diameter, pile embedment depth and soil compressive strength. |
