Stability of slope against landslide hazard

Avalanches is a process of mass movement of land and / or mass destruction of rocks of slope constituents moving down the slope due to disturbance of soil stability or rock composing slope.

The problem of avalanches often occurs due to geographical conditions in some places have high rainfall and earthquake potential areas. High rainfall is considered a major factor of sliding because water can erode a layer of sand, lubricate rocks or increase the moisture content of a clay so as to reduce shear strength. The likelihood of avalanche due to rain still has to be attributed to several factors such as local topography, geological structure, soil seepage properties and development morphology.

The hilly topographic conditions with an almost perpendicular slope lead to many unstable slopes. The phenomenon of instability of a slope can be classified into slope failure and landslide. Slope and landslide collapse can occur on a … Read more
