The process of soil deformation is a trajectory in a multidimensional space of principal stresses and principal deformations, as well as time, that is, the speed of application of deformer forces. Consequently, it is possible to achieve its destruction at various energy costs. With more rational technologies, volume deformations are minimal, and vice versa. The destruction of the soil massif should be along lines and planes characterized by the least strength. More preferred are working

... , the elements of which are executed in such a way that the sizes of the compaction zone inevitably arising as a result of their action on the soil layer are minimized. The dynamics of this process is influenced by the shape of the loading curve, the after-effect speed. The evaluation of efficiency with continuous oscillation by constant amplitude and frequency did not reveal the maximum of the energy efficiency. A promising direction is the additional oscillation of the working organ by single impulses. The construction of a soil-working working organ, self-adapting to changing operating conditions, is proposed. On the basis of the equation of motion, factors influencing the quality and energy costs of the loosening of the soil are established. Design changes are proposed to improve efficiency.
