The Influence changes of moisture soils and rocks on the formation of landslides
Jan Jaremski

Abstract
Landslide and mud avalanches have been analysed in the paper. It is confirmed that a fundamental number of the slides occur in the weathered rock of the Carpathian Flysch. Rocks occurring in this area are of the sea origin and are calcite-clayey mixtures. These mixtures, especially when weathered, are characterized by exceptional sensitivity to changes of water content which decidedly influences their strength parameters. The results of varied research including microstructural tests carried out by means of the SEM, X-ray diffractometry, X-ray fluorescence, in situ investigations and laboratory tests on prepared samples, can present methodology proposals for researching these rocks. These investigations indicate how genetic and climatic variations occurring in other regions influence the strength parameters of the rocks. Some new research directions are possible owing to the methods applied. For example computer simulations performed with the program GEO-SLOPE are really helpful. Their aim is to search for the strength parameters on the landslide failure planes for which the coefficient of safety is close to one.
