Abstract

Rockfall is an alpine phenomenon and must be understood as a risk. Due to the large number of events, detailed geotechnical investigations are not possible in many cases. In this article, a processing workflow is presented that enables an evaluation of a natural rockfall trigger risk. The trigger risk as well as the extent of damage are categorized in a risk matrix. The study of 485 outcrops at several rock slopes shows that without groundwater influence, predominantly stable conditions exist; with groundwater, the stability drops by around 20 %. In the case of a risk value of the "high" class, individual case assessments are necessary; in the case of the "medium" classification, organi- zational measures are required to minimize liability.
