Traditional design Factor of safety

Use lumped fdctors Fundrained = 1.5 cmd Fdrained = 1.3

Verification of strength for short-term (undrained) conditions cuk

Stability number (undrained) Nu =-= 0.208

Fundrained x Yk x H

From Taylor's chart, the maximum design slope angle is Pd = 72.5°

Degree of utilization is

The design is unacceptable if the degree of utilization is > 100%

Verification of strength for long-term (drained) conditions c'k

Stability number (drained) N =
