Sažetak
The paper compares the engineering geological parameters of Croatian flysch deposits and Hungarian marls with respect to slope stability. Eocene flysch deposits are widespread sediments in Central Dalmatia. They form gentle to steep slopes in the countryside and in urban areas, with risks of slope instability. Especially weathered and long-time exposed open cuts are endangered. The rock mechanical parameters vary significantly: uniaxial compressive strength from 5 MPa (clayley marl) to 80 MPa (sandstone). In Hungary Eocene marl is common lithology in the broader area of Budapest. The mean UCS of clayey layers is 4-5 MPa, but calcareous marl has a UCS up to 45 MPa. Slope instability is pronounced by small-scale landslide in un-vegetated slopes and also on covered slopes of weathered marls. Besides laboratory analyses of rock mechanical parameters shake table tests are also possible to assess the seismic behaviour of these materials. Large scale laboratory tests can be used to analyse slope stability on small scale model.
