Stability number method
It is the method used to evaluate slope stability for homogeneous soils having cohesion.
It is based on the principle resistance of soil mass against sliding, because of cohesion and internal friction acting over the failure plane.
This failure surface is assumed to be a circular arc. The factors affecting the stability of soil slope is expressed with the parameter stability number.
The stability number (Sn) is given by
Where,
c is Unit Cohesion, cm is unit mobilized cohesion
H is the vertical height of the slope
Hc is the Critical height of the slope
F is a Factor of safety with respect to cohesion
