Evaluation of Anthropogenic Substrate Variability Based on Non-Destructive Testing of Ground Anchors

Area of Science:

• Geotechnical Engineering
• Soil Mechanics
• Rheology

Background:

• Geotechnical construction design requires consideration of soil heterogeneity.
• The Warsaw Slope presents complex geological and geomorphological conditions with anthropogenic soil layers.
• Ground anchors were installed in soils of anthropogenic origin for excavation protection.

Purpose of the Study:

• To describe the variability of soil rheological properties.
• To analyze load test data from ground anchors under complex geotechnical conditions.
• To characterize man-made embankments using a rheological model.

Main Methods:

• Load tests were performed on ground anchors.
• Geostatistical methods were used to confirm subsoil randomness.
• A standard solid rheological model with nonlinear fitting was applied.

Main Results:

• Subsoil randomness was confirmed through nondirect geostatistical methods.
• A rheological model accurately described the creeping activity of ground anchors.
• Parameters from the rheological model characterized the anthropogenic embankment soils.

Conclusions:

• Soil rheological properties exhibit variability under complex geotechnical conditions.
• Rheological modeling provides an accurate method for describing soil behavior in anthropogenic embankments.
• Understanding subsoil randomness is crucial for designing stable geotechnical constructions.
