DESIGN OF A SLAB FOUNDATION WITH VERTICALLY REINFORCING ELEMENTS

The This article addresses the construction of high-rise buildings on loess collapsible soils stabilized with reinforcing elements. The primary objective of this study is the scientific and methodological justification of the effectiveness of reinforcing the base of a slab foundation for a multi-story building with vertical elements. The novelty of this research lies in the enhancement of the subgrade reaction coefficient through the design of the reinforcement grid parameters and the reinforcement length within the soil mass to ensure load-bearing capacity and reduce the settlement of the slab foundation. The design methodology is based on the requirements of Eurocode 7. Numerical simulations were performed using the finite element method (FEM) in the PLAXIS 3 software, employing the Hardening Soil model to simulate soil strengthening. As a result of increasing the subgrade reaction coefficient by incorporating rigid vertical reinforcing elements, the load-bearing capacity of the foundation was doubled. The findings substantiate the efficiency and reliability of the vertical reinforcement method for creating artificial foundations, significantly reducing both construction time and costs.
