Abstract


VARIABILITY OF THE PERMEABILITY COEFFICIENT DEPENDING ON HYDRAULIC GRADIENT EXEMPLIFIED BY GLACIAL TILLS FROM RÓŻANKA

Abstract. The paper focuses on the problems of determining the permeability coefficient, one of the important criteria for selecting the ground as a sealing material. The research program included three series of measurements of the permeability coefficient on samples from North-Polish complex till, using different conditions of stress and hydraulic gradient. The results show a considerable variability of the coefficient depending on the studied conditions, which indicates the need for research to clarify the existing guidelines for permeability studies.
