Abstract
The topic of predicting the bearing capacity of foundation structures is relevant for the entire construction industry, which plays the most important role in all branches of the country. The aim of the work is to improve the mathematical apparatus of the numerical method of boundary elements in applied studies of the behavior under load of reinforced foundations.
Soil mechanics serves as a theoretical basis for calculations when choosing the type and size of the foundation of a building, as well as when designing soil structures. Therefore, the level of development of soil mechanics significantly affects the efficiency and reliability of the decisions made. Design engineers, when it is necessary to take into account the interaction of a structure with the soil, face great uncertainty and empirical evidence. Since soils are dispersed formations, they are characterized by significant structural heterogeneity and a significant dependence of their characteristics on the level of external influences; they are a natural substance.
As a method of analyzing the problem, a modern numerical MGE was used, which allows to sharply increase the level of adequacy of the design solution, to improve the calculation scheme. The practical value of the conducted research should include a reliable picture of the “load-settlement” graph obtained by MGE for disperse soils of a construction site for analyzing the forecast of the safe limit state of a building on reinforced foundations. The current state of development of soil mechanics is characterized by an active transition to new calculation models that more fully reflect the real disperse properties of soils. Experience in designing foundation structures using numerical MGE is useful for engineers, students, and graduate students in construction specialties working in the field of soil mechanics and its practical applications.
