This article presents the results of a numerical analysis of the effect of crushed stone piles on the development of negative friction forces along the lateral surface of a single working pile; the forces are caused by the compaction of the surrounding soil due to the overloading of its surface. The adopted three-dimensional model was verified by comparing the results obtained with the published results of centrifuge modeling. The influence of crushed stone piles on the distribution of shear stresses on the lateral surface of the foundation pile and on the distribution of axial forces in its sections before and after the application of the projected vertical load were investigated. It was revealed that the negative friction forces on the lateral surface of the foundation pile decrease with the acceleration of the consolidation process of a weak water-saturated massif.
