The article presents the ability of the technical condition of buildings and structures of energy facilities in areas with unstable soil and a high level of groundwater. A method for determining the energy of a falling hammer when a pile is immersed in the ground, the height and speed of the fall of the impact part of the hammer, as well as the energy constant A (J/kg) and α (J/s), on which all energy calculations are based, are considered. Calculations for testing driven piles are given. static load. The energy hidden in the soil increases with increasing layer thickness, and this makes it possible to determine the stress in the soil at various depths from the surface.
