The artcle presents a dymanic model of a base of a structure that takes account of interal properties of soils. The properties in question are an important factor to be taken into account in the course of analysing structures together with the bases subjected to dynamic loads.
The article describes the motion of the construction foundation slab as a rigid body with six degrees of freedom on the surface of the inertial linearly deformable semi-space. The dynamic mechanical model of the base is presented as six pairs of parallel-connected springs and dampers that characterize the rigidity of the base subjected to ultimate forces (three forces alongside the axes and three moments in relation to the axes).

The wide use of reinforced foundation pads is complicated because of the absence of technical rules and regulations on design of such structures. It is necessary to investigate the main parameters and regularities of such structures operation under loading. For this aim numerical study of the foundation was carried out, the parameters of which were improved by reinforced foundation pad. The numerical modeling of reinforced foundation pads was carried out in the Plaxis 2D for study of the basic laws and operating parameters and for determination of the application area of these structures. The main goal of this study was to establish the optimal structures of reinforced foundation pads. This goal was achieved by solving the following tasks: determination of the optimal parameters of reinforced foundation pads; study of the stress-strain state of reinforced foundation pads and a soft base; estimation of the load, at which the ultimate settlement is achieved for all types of reinforced foundation pads. It was concluded that the lower reinforcement separating layer allows increasing the loading of the foundation. The typical and optimal reinforcement spacing were specified and analyzed.
