The paper presents the results of mathematical modeling of the behavior of a single conical bore injecting pile from the action of static compressive loads, as well as the effect of physical and mechanical characteristics of soils on its draft. The study was carried out by the finite element method in a nonlinear setting, taking into account the slippage of the soil along the contact surface of the pile. Comparative assessments are given on the example of the calculation of a single conical drilling-injection pile, and quantitative dependences of the effect of the characteristics of clay soils on its bearing capacity are shown.

The paper discusses the influence of geometrical parameters of tapered CFA piles in their settlement. The results of calculations of single CFA piles by finite element method under static compressive loads in clay soils . A comparative assessment of the effect of the length and angle of the side surface of the conical faces CFA piles on her draft. The example shows the effect of the angle of inclination and length of piles on their draft, as well as compares with precipitation cylindrical piles of similar material intensity.
