STABILITY AND MOTION ANALYSIS
OF THE VAIONT SLIDE
University of British Columbia, Canada
Old technology: Method of Slices
1) Work out the equilibrium of each slice
2) Calculate the equilibrium of the slice assembly
3) Results depend on assumptions regarding the
interslice force X (mobilization of internal strength)
1) Landslide was highly asymmetric
2) Internal strength contributed to the stability of typical
sections, to a limited extent
3) The structural constraint on the right flank was
4) Cohesion of the intact rock mass played an
important role, but is difficult to quantify
5) The speed of the landslide is not difficult to explain
and was due largely to the loss of cohesion in the
interior and in the side constraint
6) The slide may have been slower than assumed
7) A two-stage failure mechanism is very plausible
