SLOPE STABILITY<br />
Safety Factor (SF) = The ratio of resist<strong>in</strong>g forces<br />
to driv<strong>in</strong>g forces:<br />
Resist<strong>in</strong>g Forces<br />
SF =<br />
Driv<strong>in</strong>g Forces<br />
If SF > 1 then SAFE<br />
If SF < 1 then UNSAFE<br />
NOTE: A safety factor of ~1.25 or somewhat higher is<br />
acceptable for slope stability. A safety factor of ~10 is<br />
often used <strong>in</strong> build<strong>in</strong>g design to accommodate slight<br />
variances <strong>in</strong> materials and construction practices.<br />
