Stabilization of Slopes.

If a slide is being stabilized by flattening the slope or by using a buttress or retaining structure,  the shear strength at time of failure corresponding to a factor of safety of 1 should be calculated.  This strength can be used to evaluate the safety factor of the slope after stabilization.  Methods for stabilizing slopes and landslides are summarized in table 8-1.  Often one or more of these schemes may be used together.  Schemes I  through V are listed approximately in order of increasing cost.
