What is a slip circle?
With slip circle methods the foundation fails by rotating about some slip surface. The slip surface is taken as the arc of a circle. Almost all foundation failures showing rotational effects. The actual centre of rotation is slightly above the base of the foundation and to one side of it as shown in Figure 4 (b).
What is factor of safety slope stability?
The slope stability safety factor refers to the ratio of the soil shear strength to the shear stress of a possible sliding surface in the slope.
What is stability number?
Stability number method: It is the method used to evaluate slope stability for homogeneous soils having cohesion. This method is proposed by the Taylor. It is based on the principle resistance of soil mass against sliding, because of cohesion and internal friction acting over the failure plane.
What is mobilized shear stress?
Mobilized shear strength: The amount of shear stress/resistance developed due to the load in order to resist the deformation for all the loads less than the maximum possible load (failure) is called mobilization shear strength.
What is slope geology?
A slope is an inclined ground surface which can be either natural or human-made. Slope stability refers to the condition that an inclined slope can withstand its own weight and external forces without experiencing displacement.
What causes slope failure?
Slope failures occur when driving forces overcome resisting forces. The driving force is typically gravity, and the resisting force is the slope material’s shear strength. When assessing a slope’s stability look for indications that physical processes are decreasing shear strength.
What are the three types of slope failure?
Types of Slope Failures
- Translational Failure.
- Rotational Failure.
- Wedge Failure.
- Compound Failure.
What is slice method?
The method of slices divides a slope into multiple two-dimensional stripes, or slices, and the driving and resisting forces are calculated for each slice. This method considers both circular and planar slip surfaces (e.g., Bishop, 1955; Sarma, 1973).
How many types of slope failure are there?
Types of slope failure in geotechnical engineering
- Rotational failure. When rotational failure occurs, the failed surface will begin to move outwards and downwards.
- Translational failure.
- Compound failure.
- Wedge failure.

What is stability chart?
The stability charts allow to determine the factor of safety without any iterative procedure and identify the corresponding critical slope failure mechanism. A slope example is employed to illustrate the application and reliability of these stability charts.
