Types of Slope Failure

Damage to the road causes slope failure. A rock slope undergoes this mode of failure when combinations of discontinuities in the rock mass form blocks or wedges within the rock which are free to move.

TYPES OF SLOPE FAILURES There are main four types of failures which are.

. Types of slope failure. The slope failure occurs along the compound failure surface. An earth Slope or soil slope is an inclined surface of soil mass which can be either natural or man-made.

The failure surface that is curved at the two ends and plane in the middle portion is known as the compound failure surface. A translational slide occurs when a slope fails along a weak zone of the soilAfter sliding for a considerable amount of distance the mass can rest. While these types of failures tend not to be catastrophic in nature they can be detrimental to human health and the environment and costly to repair.

What is shallow slope failure. A plane b wedge c circular and d toppling. The pattern of.

Different types of slope failures and shape of their failure surfaces are discussed below. Because of sudden collapse of slope many people fail to escape from it if it occurs near a residential area thus resulting in a higher rate of fatalities. Effects of Slope Failure.

This type of slope failure commonly occurs when a hard stratum exists below the toe at a considerable depth. The intersection of planar discontinuities in the rock mass with the surface slope is predisposing toward plane and wedge failures. The types of slope failure are primarily controlled by material properties water content and foundation strength.

32 Plane failure. Slopes expose two or more free surfaces because of geometry. A slope failure is a phenomenon that a slope collapses abruptly due to weakened self-retainability of the earth under the influence of a rainfall or an earthquake.

TYPES OF ROCK SLOPE FAILURE 31 Introduction Slope failures are major natural hazards that occur in many areas throughout the world. Common types of slope failure. It reduces the bearing capacity of the soil.

Types of Slope Failures Translational Slide. Plane Failure A rock slope undergoes this mode of failure when combinations of discontinuities in the rock mass form blocks or wedges within the rock which are free to move. Whereas loads placed at the bottom of the slope also called the berm zone are much better handled by the slope.

Because of a sudden collapse of the slope many people fail to escape from it if it occurs near a residential area thus resulting in a higher rate of fatalities. Types of slope failure fPlane failure Typical view of Plane failure fPlane failure with condition of failures fPlane failure with condition of failures The dip direction of the planar discontinuity must be within 20o of the dip direction of the slope face The dip of the planar discontinuity must be less than the dip. Failure surface moves outwards and downward.

A slope failure is a phenomenon that a slope collapses abruptly due to weakened self-retainability of the earth under the influence of rainfall or an earthquake. Rotational slides with their central point of rotation parallel to a slope are common types of soil failure in homogeneous fine-grained soils. The pattern of the discontinuities may.

It is classified into four types. Translational failure 3. In similar soils the shape is circular while.

Types of Slope Failure. It significantly affects humans and their lives. When the slope breaks along a specific line along the length of the slope on a weak zone it is called a translational slide.

Types of Slope Failure. The broken down part may remain largely intact and slide. Shallow translational failures occur along the weakest interfaces and shallow rotational failures occur through the weakest layers of a slope.

Weak or fragmented rock like soil may fail in. Plane wedge toppling rockfall and rotational circularnon-circular types of failure are common in slopes Figure 1. In this case of rotational failure the failure occurs by rotation slip surface and the shape thus obtained in slip surface is curved.

21 are shown four types of failure of rock slopes. Slope failure causes landslides that may cause loss of life and properties.
