The comprehensive studies’ results of the soil environment stress-strain state from the loaded and unloaded foundation model action are considered and compared: 1. Laboratory experiments with foundation models were carried out, on the basis of which a numerical SSS soil foundation analysis was carried out, empirical relationships between the influencing parameters and the foundations’ additional settlement amount due to their mutual influence on each other were obtained. 2. Numerical modeling of foundations located in the mutual influence zone by the finite element method of numerical research using the software package Plaxis 3D was performed. 3. A numerical analysis of the influence of the distances between the stamps’ axes on the additional stresses’ values from the loaded foundation is given using the method of angular points, as a method recommended by the current regulatory documentation [13]. These results can be used to refine the existing calculation methods. The difference between the results of numerical and experimental modeling is noted.
