The comparisson of material properties of debris flows from Stože, Slano blato and Strug landslides

Abstract

The three large landslides that occured in Slovenia in past few years and threaten the population and infrastructure were relatively well investigated geologically and geomechanically. One of common characteristics of all three landslides is the occurence of fast debris flows. One part of laboratory investigations was therefore focused into the study of materials that under given circumstances transform into debris flow. In addition to standard geomechanical investigations their behaviour was tested also in rheometer. In the paper the results of all laboratory tests are compared for the mentioned three landslides. The results of rheometer tests showed a consistency between test results and material behaviour on site for two tested materials.
