Negative FOS for slope stability in planar failure slopes
Negative FOS for slope stability in planar failure slopes
(OP)
When I calculate the factor of the safety for a slope with a discontinuity which meets all the criteria for planar slope failure it comes out as -0.69 what does this mean ?

The FOS should be the ratio of resisting forces to driving forces -- neither quantity should be negative, so the FOS should not be negative.

Check all of you normal forces. Are they all positive?
