  • Failure Modes in Rock and Soil Slopes Slope Failure

    Failure Modes Introduction. Slope failures are essentially natural hazards that occur in many areas over the world. Popularly known as landslides slope failures describe a wide variety of mechanisms that cause the outward or downward movement of slope-forming materials like rock soil or landfills.Landslide can result either from rock failure or soil failure.
