In the article there are results of modeling of the work of steel concrete screw and drilling piles interacting with the soil massif . For the purpose of modeling the mathematical apparatus of finite element method was used in realization of the license certified program complex Lira- soft v.10.6. The process of modeling of the subsidence is described. There is a presentation of three options of interaction of soil and piles. Draft magnitudes of single piles from external load and from negative friction forces are found.
