Types Of Slope Failures
Failure occurs by rotation along a slip surface by downward and awkward movement of the soil mass.
- Occurs in an infinite slope along a long failure surface along the slope.
- A constant slope of unlimited extent and having uniform soil properties at the same depth below the free surface.
- Shape of failure plane is affected by presence of hard substartum at the shallow depth.
- May occur along the slope of stratification.
3. Compound Failure
Combination of rotational and translational failure.
Hard stratum at considerable depth.
Occurs when distinct blocks and wedges of the soil mass get separated.
Occurs in finite slope with layers of two different materials or a homogeneous material with cracks.
