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

Abstract

The purpose of this paper is to describe the variability of soil rheological properties based on research carried out using load tests of ground anchors under complex geotechnical conditions. The heterogeneity of soil should always be considered when designing geotechnical constructions. In the present case, the earthwork created at the Warsaw Slope revealed an embankment of anthropogenic origin, located in a geologically and geomorphologically complex area of the Vistula valley slope. Excavation protection was anchored mainly in soils of anthropogenic origin. When the acceptance tests of the ground anchor were completed, the subsoil randomness was confirmed using nondirect, geostatistical methods. A standard solid rheological model with nonlinear fitting to the data was used. This model was established to describe the creeping activity of the ground anchor more accurately. The characteristics of man-made embankments were described using the parameters obtained with the rheological model of the subsoil.

Renewable-Resource Technologies in Mining and Metallurgical Enterprises Providing Environmental Safety

“…For a highly efficient implementation of renewable-resource technologies with the complexity of the development of georesources, it is necessary to take into account the variability of anthropogenic formations [51] and the requirements of environmental safety at the design stage of a mining and processing enterprise.…”
