The article presents the results of the depth study of compressible thickness of the base in a full-scale experiment where a hard round stamp with a diameter of 800 mm served as a foundation model. Loading was made by steps of 0.05 MPa, the load is maintained until stabilization of the sediments. We studied the development of deformities and change of the lower limit of the compressible strata of a silty loess foundation folded in slightly wet macroporous loams with increasing load, we fixed displacements of deep marks in the process of loading, a deformation of the base was analyzed. Also, the fields of soil density were built before deformation and the deformed base. During the study of bundle movement in the array loess grounds, we made conclusions about changes in precipitation, the lower boundary of a compressible base thickness and about changing of soil density.
