The paper presents the capacity of driven precast pile prediction method based on the results of CPT tests. The pile settlement equal to 10% of pile diameter is assumed as a criterion of pile capacity. The method gives also a unit skin friction and a unit base resistance for intermediate pile settlements. This allows us to simulate the load-settlement curve and to calculate the axial stiffness of the pile in any load range. For the purpose of analysis the calculation file is created which makes it possible to compare the results of calculation with those of the field-test. The comparative analysis of 37 square 0.3 m × 0.3 m and 0.4 m × 0.4 m piles in clays and sands was carried out. The comparison shows a good agreement between the predicted and actual capacities and a satisfactory agreement between the predicted and actual slopes of the load-settlement curve in the range up to 40% of the ultimate pile capacity.
