AN EVALUATION OF SLOPE STABILITY CLASSIFICATION

An overview is given of a series of classification systems used for rock slope stability analyses. Calculation methods and parameters used seem not always appropriate for slopes stability and could be improved. Based on this evaluation some new ideas developed of how a system for slope stability assessment could be designed without inherited legacies as parameters related to underground excavations. In the past classification system calculations should be simple as these were supposed to be done on site in the field. With the general availability of palmtop computers this restriction is not necessary anymore and more sophisticated systems with more complicated calculations can be designed which may result in better slope stability predictions.
