A NEW ANALYSIS PROCEDURE TO EXPLAIN A SLOPE FAILURE AT THE MARTIN LAKE MINE. DISCUSSION

The discusser, R.L. Michalowski, notes that the authors utilize the upper bound (kinematical) approach of limit analysis to evaluate the stability of slopes, taking into account the pore pressure in the soil mass. They have developed a failure mechanism which includes both rigid rotation and shear deformation (plane strain), but the discusser does not agree with the authors' method of calculations. It is argued that the calculations of the the energy dissipation rate in the plastic deformation process are incorrect. The discussion is followed by a reply by the authors.
