Interaction of the pile with the sagging loess soil

Abstract

The article presents the formulation and solution of the problem in the interaction of a pile with a two-layered base, the upper layer of which settles due to the moistening by the filtrational flow (Darcy's law) or moisture transfer (Fick's law), and the lower layer is bearing, possesses relatively strong and deformation properties, which pushes against. It is shown that due to subsidence of the surrounding soil, negative friction occurs on the lateral surface of the pile, which causes additional draft and force at the level of the heel of the pile. As a calculation, the geomechanical model of the ground cylinder, containing the pile and perceiving the load from the grillage as part of the pile-slab foundation, is considered.
