The results of laboratory research of formation and development process of limit state areas in the basis of box-shaped foundation on the models made of XC gelatin-gel are provided in the article. The models have different forms and they are made of organic glass from gelatin-gel that has three different gelatin concentration, and then these forms were put into formaldehyde solution for tanning. Loading of models until the time when limit state areas appear is carried out in the same forms. Graphic dependences of the intensity of evenly distributed loading corresponding to the moment of the beginning of destruction, on the relation of the width of the foundation model to the depth of its location at various gelatin concentration in the material used for models are received. The comparison of the experimental data to the data of calculations performed with the help of the computer program “Stability. Stress-Strain State” and on the basis of the developed in VSUACE engineering method showed their satisfactory convergence.
