The article presents the results of a comparative analysis of practical calculations of driven and bored piles, which have similar geometric parameters and common geological conditions of construction sites. Taking into account the peculiarities of the use of these piles and the available experimental data, the paper analyzes the calculated values of their bearing capacity and gives an engineering assessment of the results of the calculation. The quantitative difference between the determined parameters of the bearing capacity of piles - friction along the lateral surface and frontal resistance, is clearly shown in the constructed diagrams. So, when using the standard values of the coefficients to determine the bearing capacity of piles, we have a significant excess of this parameter for driven piles. The need to use more gentle methods of driving piles to the design depth leads to the possibility of using the technology of arranging bored piles, which have a lower bearing capacity with the same parameters as driven piles. This feature should be taken into account in engineering calculations when selecting the optimal dimensions of bored piles.
