“…При строительстве автомобильных дорог немаловажное значение имеет уплотнение различных конструктивных слоев. При этом большое внимание уделяется уплотнению грунтов естественного сложения нижнего основания 1 [1,2]. Такие грунты обычно имеют недостаточную плотность, но повышенную прочность сцепления между отдельными агрегатами грунтового полупространства 2 , что требует приложения к ним нагрузок, превышающих пределы прочности уплотняемого материала.…”

Introduction. During the construction of modern highways, much attention is paid to compaction of bases consisting of natural soils. They require the use of special equipment, including self-propelled machines, performing compaction in a continuous cycle. But when designing it, certain difficulties arise in determining the parameters of impact accelerators and the mass of the impact plate. The purpose of the work is to study the influence of the parameters of working equipment on the process of soil deformation.Materials and methods. To check the influence of the parameters of the tamper equipment on the compaction process, a method of mathematical modeling of the process using rheological models was chosen. The working cycle of impact ramming is divided into four phases. A mathematical description of the movement of the stamp and soil in each of the phases of movement is given. The change in the stress condition in time in the body of the soil half-space is considered.Results.Тhe time dependence of the soil stress condition was obtained for different stiffnesses of the spring impact accelerator and the change in the stamp mass. A joint analysis of the obtained dependencies showed that when designing impact equipment intended for compaction of naturally occurring soils, it requires matching the peak stresses from the mass of the stamp and the stiffness of the impact accelerators. This will make it possible to stretch the action of stresses in time, to form a compacted core in the soil half-space quickly and require a smaller number of strokes on one track to obtain the required material density.Discussion and conclusion. The proposed model of tamper equipment made it possible to consider the processes occurring in the soil half-space, to obtain comparative characteristics of the stamp mass and the rigidity of impact accelerators. The obtained data correlate well with the data of other authors. The results of the study may be useful to engineers involved in the development of new techniques of intensifying action.Financial transparency: the authors have no financial interest in the presented materials or methods. There is no conflict of interest.

In this paper, complex signal analyses of ground penetrating radar (GPR) field data over an area of farmland in Krakow were interpreted alongside the basic filtered field data. The farmland was simulated with var-ying degrees of soil compaction induced by tractor movement. The focus of the study was the delineation of in-herent characteristics of media through which the electromagnetic energy travelled. Fourteen GPR profiles were acquired from the area. The field data were subjected to pre- and post-processing prior to its the presentation and interpretation. Advance analysis operations on the field data which resorted in different attributes reveal more about the effects of the compaction on the soil than indicated by the basic filtered field data. Better resolution of subsurface layers boundary and lateral variation in the physical properties of the traversing media were well elu-cidated. The results have demonstrated that an advanced signal processing such as used in the study has ability to depict subtle characteristics of the propagating media.
