Differences in Determination of Bored Pile Compressive Resistance in Slovakia and Poland

The paper deals with differences in determination of bored pile compressive resistance in Slovakia and Poland. Common procedures of determination of bored pile compressive resistance, applied in Slovakia and Poland, will be introduced. It will be shown in examples that various calculation procedures take into account various factors influencing pile compressive resistance in different way, therefore pile compressive resistances determined by various procedures will be different. It will be also shown, that underground water has strong impact on pile compressive resistances so reliable determination of its presence and its change during pile life can contribute to economic pile design.
