What factors cause slope failure?
The increase in the shear stress that ultimately causes the failure of soil.
- Decline in Shear Strength of soil. Several factors can result in a decreased shear strength of the soil.
- Increase in Shear Stress of Soil.
What are 3 factors that make slope failure more likely?
Common Causes of Slope Failure
- Steepness of the Slope. It goes without saying that the steeper a slope is, the more unstable it will be.
- Water and Drainage. Water is several times heavier than air.
- Soil Composition.
- Joints & Fractures.
What is the most common slope failure?
4 days ago
When the slip surface intersects the toe of the slope, it is called toe failure. It is the most common failure.
What are the different types of slope failure?
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 are types of slope failure?
Soil slope failures are generally of four types : Translational Failure. Rotational Failure….Rotational Failure
- Face failure or slope failure.
- Toe failure.
- Base failure.
What are slope failures?
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. Weathered geology: Weak, weathered bedrock, jointed rock, or bedrock that dips parallel to the slope can decrease stability.
What are the types of slope failures?
What are 4 types of slopes?
From the previous section, you have discovered that there are four types of slope.
- postive slope (when lines go uphill from left to right)
- negative slope (when lines go downhill from left to right)
- zero slope (when lines are horizontal)
- undefined slope (when lines are vertical)
What is depth factor in slope stability?
b) Slope depth. c) Depth failure. d) Base failure. Explanation: The ratio of the total depth (H + D) to depth H is called the depth factor Df.
What are the types and causes of slope failure?
Causes of Slope Failure.
- Erosion. Water and wind continuously erode natural and man-made slopes.
- Rainfall. Long periods of rainfall saturate, soften, and erode soils.
- Earthquakes. Earthquakes induce dynamic forces (Figure 16.3d), especially dynamic shear forces that reduce the shear strength and stiffness of the soil.
What is the most common type of slope failure?
Toe failure
Toe failure is the most common situation and it occurs when the failing surface passes through the slope’s toe.
