Мелашенко Ю. Interaction of pile foundations with the ground base at a vertical loading.

The thesis is devoted to such aspect of pile foundations interaction with basis, as determination of piles settlements and pile foundations under the vertical static loading. This task is solved by approximation of dependence cap pile settlement under the vertical loading s = f (P) chart and by curve parameters search. Pile cap elastic settlement is got on the basis of problem solution about bar displacement in elastic half-space using R. Mindlin solution. This method of attack allows not only to find the loaded pile own settlement but also to determine another constructions settlement which are on the surface of soil or inside. Reliability verification of the proposed calculation procedure of single piles and pile foundations settlement in comparison with the single piles, one and two-row pile foundations field tests results, given by A.A. Bartolomey, is realized. This verification is shown, that procedure which proposed has a sufficient convergence for practical tasks. Keywords: pile, pile foundation, interaction with foundation, settlement, influence, calculation model.
