Sažetak

This paper investigates the influence of unbraced sloped excavations in cohesive soil on building
settlement through a comprehensive multiparametric analysis. Using the Mohr-Coulomb constitutive model
in GeoStudio 2024, 288 simulations were conducted to explore the impact of excavation depth, slope angle,
soil strength, compressibility, and building proximity on settlement. The results indicate that increased
excavation depth and steeper slopes significantly amplify building settlements, particularly for weaker and
more compressible soils. Conversely, greater distances between the building and the excavation edge
mitigate these effects. Findings suggest maintaining a distance of at least 2 meters for safe excavation. This
study provides valuable guidelines for geotechnical engineers to design effective excavation plans,
minimizing potential negative effects on nearby buildings.
