Ilościowa analiza morfometrycznych i geometrycznych cech mikrostruktur glin zwałowych zlodowacenia Wisły
Abstract
Szybki rozwój komputerowych technik obliczeniowych i metod cyfrowego opracowania obrazów doprowadził do powstania zautomatyzowanej analizy obrazów ze skaningowych mikroskopów elektronowych (SEM). W trakcie takich badań można otrzymać wiele morfometrycznych i geometrycznych wskaźników mikrostruktury próbki. Należy podkreślić wysoką wydajność i szerokie możliwości dla określania dowolnych parametrów mikrobudowy skał i gruntów. THE QUANTITATIVE SEM-COMPUTER ANALYSIS OF MORPHOMETRIC AND GEOMETRIC FEATURES OF MICROSTRUCTURES IN BOULDER CLAYS OF THE V1STULA GLACIATION IN THE AREA OF POLAND The paper presents the results of quantitative microstructural analysis of boulder clays of the Vistula Glaciation. Totally 16 tests have been carried out in two series of eight for Pomeranian Phase and Leszno Phase. The results of the analysis are shown in the Table 1 and 2, which present morphometric and geometric parameters of microstructures in the boulder clays. The results reveal clear tendency of bigger values of the parameters in Leszno Phase which indicates looser character of the microstructures in the boulder clays of this phase. This allows to submit a proposition about less degree of consolidation of these soils. On the other hand a little higher anisotropy coefficient of the microstructures (Ka) for Pomeranian Phase testifies better orientation of younger deposits.Downloads
