Rozpoznanie stref dopływu wody podziemnej do wykopu pod fundamenty nowego budynku ACK CYFRONET AGH w Krakowie z wykorzystaniem metody konduktometrycznej

Abstract

Application of the ground conductivity meters to finding groundwater leak zones in the foundations of the new-built AKC CYFRONET building, AGH UST, Cracow.A b s t r a c t. Electrical conductivity is used in the study of fresh-water and/or mineralized water outflow zones. Conductivity of water is relatively low. It strongly depends on its salinity and mineralization. Increased salinity and mineralization of water give rise to conductivity growth of hydrogeological medium. Finding water leak zones is an important problem during planning any building works. The influence of water on the building can be disadvantageous (elution, destruction of the foundations and sulfate aggressiveness). Because of high conductivity of water, watered zones can be recognized with the use of electromagnetic methods. The paper presents results of examination of mineralized water leak zones on the building site of the new CYFRONET building in the Ruczaj quarter, Cracow, Poland. The examinations were conducted with the use of ground conductivity meters. The main goal of the research was to find mineralized water leakage under the foundations of the new-built building.
