Types Of Rock Slope Failure

The types of slope failure are primarily controlled by material properties water content and foundation strength.

Types of rock slope failure. Block toppling and 3. 2 3 2 plane failure. It is the slope failure that occurs by the rotation along a slip surface usually by the downward and the outward movement of the soil mass. Slope stability refers to the condition of inclined soil or rock slopes to withstand or undergo movement the stability condition of slopes is a subject of study and research in soil mechanics.

This types of failures generally occurred in nature where the bed of rocks is found below the certain depth of the soil mass along the slope and soil above it slide due to a decrease in the bond between them. The removal of overburden and the confining rock as is the case in mining excavations can result in a partial relief of the constraining stresses within the rock structure resulting in a toppling failure.

Block and damage of road may occur due to slope failure.

Rock and soil slopes are weakened through saturation by melting snow or heavy rain. Water filling the pores of permeable materials allows the grains to slide past each other with little friction. Water acts as a lubricant increasing the ease of movement of rock and soil particles and therefore slope failure. Types of slope failure.

In general slope failure can be classified into the following four types. An earth slope or soil slope is an inclined surface of soil mass which can be either natural or man made. Common types of slope failure. Different types of slope failures and shape of their failure surfaces are discussed below.

Failure of a slope along a weak zone of soil is called a translational slide figure 16 2a. This type of slope failure may be further categorized depend on the mode such as. Slope failures depend on the soil type soil stratification groundwater seepage and the slope geometry. 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. We will introduce a few types of slope failure that are common in soils. Circular failure occurs in soil mine dump heavily jointed or fractured rock mass and very weak rock. Three major types of mass wasting are classified by the type of downslope movement.
