The article presents the results of driving and static tests for vertical indentation loads of pyramidal-prismatic models and prismatic piles in laboratory conditions. It was found that with an increase in the size of the upper section of the pyramidal section of pyramidal-prismatic piles, the energy costs for their driving, as well as their bearing capacity, also increase. It was revealed that the energy intensity of driving pyramidal-prismatic piles (depending on the length and size of the upper section of the pyramidal part) can be 1.05-1.6 times higher or 36-58% lower than that of prismatic piles (with a section of 20 × 20 and 30 × 30 cm). A correlation dependence has been obtained, which makes it possible to predict the bearing capacity of pyramidal-prismatic piles with known values of the bearing capacity of traditional prismatic piles. The revealed features of the behavior of pyramidal-prismatic piles make it possible to reasonably assign the length and
dimensions of the section of their pyramidal part.
Keywords: pyramidal-prismatic pile, prismatic pile, specific energy intensity, bearing capacity, specific bearing capacity, settlem.
