The laboratory tests of models of driven pyramidal-prismatic and prismatic piles for pressing vertical loads are presented. Laboratory tests were carried out on reduced piles models (M 1:10) with different lengths and cross-sections of the pyramidal segment. It was found that with an increase in the length of the pyramidal segment of pile models, the energy costs for driving them increase by 7.12-27.26%, the bearing capacity of the pile models increases by 28.36-55.38%. It was revealed at the same driving depth and the same settlements, the bearing capacity of the models of pyramidal-prismatic piles is 1.5-4.01 times higher than the model of a prismatic pile with a cross-section of 20×20 mm, and compared to the model of a prismatic pile with a cross-section 30×30 mm can be either 1.23-1.92 times more or 8-35% less, depending on the length and size of the cross-section of the pyramidal segment of the experimental pile models. A correlation dependence has been obtained, making it possible to predict the bearing capacity of pyramidal- prismatic piles with known values of traditional prismatic piles’ bearing capacity. The revealed features of the behavior of pyramids-long-distance-prismatic piles allow to reasonably assign the length and dimensions of the cross-section of their pyramidal segment.
