Summary
The objective of this paper is to develop a predictive numerical model able to provide indications regarding the triggering of future rock falls on the Grossgufer slope. The work involves the analysis of a previous rock fall event which occurred on the Grossgufer slope during the spring of 1991. This rockslide involved an estimated volume of 30 million cubic meters of rocks and debris. Geomechanical studies and control measurements carried out by the Centre de Researche Scientifique et Applique du Sion (CRSFA) allowed the authors to set up a numerical model able to simulate the rock slope mechanic and hydraulic behavior, and correlate it to the triggering causes of the phenomenon, thus determining a warning threshold for future landslide events.
