NUMERICAL RESEARCHES OF THE WORK OF THE PILE WITH END SPHERICAL BROADENING AS PART OF THE PILE GROUP

Abstract

The article presents some aspects of the development of the theory of constructing design schemes for long pile groups with end spherical broadening and results of their numerical analysis of the load capacity of piles with end broadening in comparison with the operation of piles without widening in the Bush. As a result of a numerical analysis of the bearing capacity of piles with end broadenings in a comparative calculation with the work of piles without broadening in the bush, it was revealed that vertical and horizontal stresses in the soil mass increase with a decrease in the pitch of piles with broadenings in the group. The direction of development of deformations (compaction) of the soil and its ejection from the heel and body of the pile with and without end broadening with a pitch of piles in the bush equal to 6 d show that the ejection of the soil affected the change in the initial physical and mechanical characteristics of the base.
