Conclusions
1. The stress-strain state of the “reinforced-concrete-pile/soil” system depends on both the elastoplastic properties of the soil, and the pile material.
2. The variation in the bending stiffness of the cross section of a reinforced-concrete pile during loading should be accounted for in calculating the lateral load on these piles. Consideration of this factor will make it possible to determine the stress-strain state of the system under consideration more accurately; this will ensure a saving of concrete and reinforcement.
