Types of Slope Failure

Relatively shallow depth of failure wide and long geometry with respect to depth. 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.

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.

. What is retrogressive slope failure. In this case of rotational failure the failure occurs by rotation slip surface and the shape thus obtained in slip surface is curved. The pattern of.

Failure surface moves outwards and downward. Clear failure at transition between subsurface materials. An earth Slope or soil slope is an inclined surface of soil mass which can be either natural or man-made.

The slope of a line is assigned to the ratio of the quantity that y extends as x increases some amount. Common types of slope failure 1 32 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. 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.

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. Plane wedge toppling rockfall and rotational circularnon-circular types of failure are common in slopes Figure 1. This type of slope failure commonly occurs when a hard stratum exists below the toe at a considerable depth.

TYPES OF SLOPE FAILURES There are main four types of failures which are. A rock slope undergoes this mode of failure when combinations of discontinuities in the rock mass form. 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. The slope is the evaluation of the inclination of a line or a segment of a line that is attached with the two points. 32 Plane failure.

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. The slope failure occurs along the compound failure surface. 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. Tends to occur in gentle terrain. Slopes expose two or more free surfaces because of geometry.

The failure surface that is curved at the two ends and plane in the middle portion is known as the compound failure surface. TYPES OF ROCK SLOPE FAILURE 31 Introduction Slope failures are major natural hazards that occur in many areas throughout the world. Types of slope failure.

Tendency to exhibit only displacement at failure with limited settlementheave in body. The slope is unvarying equivalent anywhere on the line. The types of slope failure are primarily controlled by material properties water content and foundation strength.

Rotational slides with their central point of rotation parallel to a slope are common types of soil failure in homogeneous fine-grained soils. A plane b wedge c circular and d toppling. Common types of slope failure.

Headscarp tends to be less curved. In similar soils the shape is circular while. Depending on the construction the slope is.

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. If an initial slide occurs and the material in the failure flows away which is usually caused by a high degree of strength loss a steep main scarp will usually be formed and therefore support for the remaining soil will be removedThis can result in another failure termed a retrogressive failure. 21 are shown four types of failure of rock slopes.

Different types of slope failures and shape of their failure surfaces are discussed below.
