The problem of determining reliable characteristics of soils necessary for the design of foundations of buildings and structures is important and urgent. The main parameters determining the mechanical properties of soils are their strength and deformation characteristics, obtained, as a rule, by the results of static probing. Investigations of the process of probe immersion into the soil have allowed to identify a zone of fracture, within which shear deformations take place; a zone of elastic-plastic shear deformations and a zone of elastic deformations. This obviously leads to a change in the determined soil parameters around the probe. Comparing the interaction of the pile and the surrounding soil with the processes occurring during the probe immersion, the values of the obtained characteristics of sandy soils during probing are revealed with their values for the sands of natural composition, which allows to obtain more reliable values for the design of bases and foundations. The article examines the features of the interaction of the surrounding soil with piles and a probe during their immersion, associated with a change in the porosity coefficient.
