    2019-12-21The term landslide or less frequently, landslip, refers to several forms of mass wasting that include a wide range of ground movements, such as rockfalls, deep-seated slope failures, mudflows, and debris flows.Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are ...

    Landslides triggered by excavation in the loess

    In this identification process, historical images of every landslide in the Loess Plateau have been carefully checked, where a landslide would be screened out if excavation activities were found to be carried out on the slope before the failure of such a slope.

  • Human-induced landslide on a high cut slope a case

    Human-induced landslide on a high cut slope a case

    The paper attempts to represent a case of repeated failures on a high cut slope due to multi-excavation. The characteristics of each failure induced by excavation are analyzed through geological investigation, and then a geological model at different failure stages is proposed.

However, frequently the dominant factor which triggers the movement of slope material will be an increase in pore water pressure from rainfall or leaking infrastructure. Other triggers include earthquakes, vibrations caused by human activities, and undercutting of slopes by fluvial erosion or artificial excavation.

    2019-12-15The causes of landslides are usually related to instabilities in slopes. It is usually possible to identify one or more landslide causes and one landslide trigger. The difference between these two concepts is subtle but important. The landslide causes are the reasons that a landslide occurred in that location and at that time.

    Vulnerability to landslide hazards is a function of location, type of human activity, use, and frequency of landslide events. The effects of landslides on people and structures can be lessened by total avoidance of landslide hazard areas or by restricting, prohibiting, or imposing conditions on hazard-zone activity.
