Conclusions
Thus, the discrepancy between the calculated and the results obtained during stamp tests can be
explained by the structural features of loess soils, which are dispersed anisotropic media.
The conducted experiments have shown that when calculating the core in low-moisture loess

soils according to the generally accepted methodology, it is necessary to take into account the features
of these soils as the foundations of structures. The proposed calculated dependences make it possible
to clarify the depth of the active (compressible) zone in the foundations of structures erected on low-
moisture loess soils and the peculiarities of stress distribution in them.
