Abstract
This paper presents a comprehensive study of a soil failure at 4 M. Hrinchenko Street, Kyiv, and the development of engineering measures for stabilizing landslide deformations that threaten the surrounding multi-story buildings. The research methods included visual inspection of active gully erosion sites and damage to a parking facility near a residential high-rise; testing of the physical and mechanical properties of slope soils for refining the initial boundary conditions and subsequent mathematical modeling of the stress-strain state of the soil mass. For these purposes, the Plaxis software package and a nonlinear soil model governed by the Mohr-Coulomb strength criterion were employed. Visual inspection revealed that the average slope angle is 20–22°, with a width of about 34 m and a length ranging from 13 to 52 m. Three active gully erosion centers were identified, along with the presence of “loess karst.” Its development is driven by the steep relief of the slope and the influence of groundwater and surface runoff. Numerical modeling showed that the overall slope stability is not ensured. At present, the existing landslide does not yet compromise the stability and reliability of the surrounding high-rise development. However, failure to implement emergency mitigation and stabilization measures could significantly worsen the condition of the territory adjacent to the building, causing damage to engineering networks and utilities (for example, a medium-pressure gas pipeline located at the foot of the slope).
