Abstract

The article presents the results of experimental and numerical modelling of slotted foundations. Model and large-scale experimental studies were conducted. The influence of the number, thickness, and depth of sinking of the slotted foundation walls on the distribution of stresses and deformations in the basis is established. The results of numerical studies show the distribution of stress and strain components at the base of slotted foundations, taking into account the elastic-plastic properties of the soil. For the estimation of slotted foundations based on the maximum permissible precipitation using solutions of nonlinear soil mechanics, the factors affecting the precipitation are identified and the corresponding approximate dependencies are obtained. The use of non-linear calculation methods makes it possible to design slotted foundations based on the ultimate deformations. These studies are confirmed by the results of experiments of various authors. Designs of slotted foundations are implemented in the construction of buildings and structures, which reduce the cost of the zero cycle, reduce the material consumption in comparison with standard solutions. The article is of interest to specialists in the field of soil mechanics, geotechnics, and foundation engineering.
