Abstract
Characteristic for forest soils under vibration impacts is the accumulation of deformation volumes over time. This is explained by the gradual accumulation of mutual shifts from each individual flare period. When the shaking frequency occurs, mutual random particles overlap and the process of their event duration occurs. Possible cases of manifestation of vibration effects in loess under various dynamic effects are analyzed. The role of the thickness of the layer lying above the groundwater level in increasing the magnitude of the soil vibroutility is noted. The accumulation of deformations in time under the observed vibrations and stresses is called vibrocreep of the soil.
