Artykuł przedstawia wyniki analizy istotności wpływu cyklicznego zamrażania-rozmrażania (ZR) oraz rodzaju systemu zamrażania na zmiany dystrybucji porów dla gruntów spoistych wybranych przy zastosowaniu wieloczynnikowej analizy wariancji. Na podstawie ilościowej analizy fotogramów SEM przeprowadzono analizę dystrybucji wielkości porów w wybranych reprezentatywnych próbkach 5 spoistych gruntów niemrożonych,...
A series of experiments on samples of five clayey soils gave evidence that cyclic freezing and thawing significantly affects the permeability coefficient. An attempt to analyze these changes on base of the Scanning Electron Microscopy SEM photographs of microstructures has been made. A simplistic equation (Eq. 11) has been drawn, describing the permeability coefficient as a function of hydraulic radius...
