The long piles interaction with the surrounding and underlying soils, taking into account the linear and nonlinear rheological properties

Abstract

Abstract The article presents the long incompressible pile with a two-layer base interaction problem formulation and solution, taking into account the underlying soil visco-plastic properties by the analytical method. A significant change in the stress-strain state at the base of an incompressible pile when stress changes around the pile side surface is shown. It is shown that in such conditions, the stress under the pile bottom varies significantly over time, which can lead to the pile bearing capacity loss in the long run.
