The article presents the results of physical modeling of slot foundations. The results of the research have established the dependence of the bearing capacity of slotted foundations on the length and spacing of the slots, and a qualitative assessment of the stress-strain state of the “slotted foundation-soil base” system has been obtained.
The results of the physical modeling were used to evaluate the performance of the foundation and soil base model in the Plaxis 3D Foundation software. Numerical modeling of the slotted foundation with different geometric
parameters was performed, 9 different schemes were considered. The dependence of the bearing capacity of the foundation on different distances between the slots and their different lengths was determined. The obtained modeling results indicate an increase in the bearing capacity of the slotted foundation (1.5-2 times) with an increase in the distance between the slots without increasing their length. This is due to the inclusion of soil, which is located between the slots.
