A finite element numerical analysis of the stress-strain state of combined precast-monolithic piles, arranged using the authors’ technology in permafrost soils, has been performed. It is shown that there is no need for reinforcing the entire length of the monolithic part located below the seasonal thawing boundary. Recommendations for the design and reinforcement of such piles, providing a reduction in metal consumption and the cost of pile foundations, are given.
