Review article

The article presents a practical method of calculation of pile foundations for vibration-active equipment with harmonic effects, the algorithm of calculation of pile foundation with bored piles, which include the determination of individual reduced elastic characteristics (compression, shear, etc.), including the determination of individual normalized elastic characteristics (in compression, shear, etc.), which allows replacing the pile foundation in the calculations with a massive foundation. The general method of calculation is illustrated with an example of the calculation of a pile foundation with bored piles for the Siemens STG 800 turbine unit. Considering the constructive solution of the support part of the unit, the vertical and horizontal-rotational oscillations can be calculated separately using impulse transition functions. There have been constructed graphs of horizontal and horizontal-rotational oscillations in the working and transition modes.
