Types Of Slope Failures

1.Rotational failure

Failure occurs by rotation along a slip surface by downward and awkward movement of the soil mass.

2.Translational Failure

• 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.

4.Wedge Failure

• 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.
