Mineralogical and Physical Properies of Typical Soils from Zagreb Podsljeme Area

Sa？etak Due to the specific geomorphology, complex geological structures and as a consequence of quick and inadequate construction of buildings, there is a problem with the stability of the slopes in the Podsljeme area of Zagreb. The numerous landslides pose a threat to the local population and their property. The greatest influence on the engineering geological conditions in Podsljeme area have fine – grained soils which occupy about 70 % of total area. Within the framework of the project "Detailed engineering geological map of Zagreb Podsljeme area M 1: 5000 - PHASE I" (abbreviated DIGK – PHASE I), research was carried out to determine the engineering geological properties of soil in the surface area of the entire sub zone up to a maximum depth of 5 m as well as deeper profiles on selected locations. The investigations included geomechanical and mineralogical analyses. Based on the obtained data and their analyzes the authors represent a clear picture of the engineering soils in the Podsljeme area and their similarity and differences in relation to the physical and mechanical properties, the lithostratigraphic affiliation and the mineralogical composition
