Abstract: First the principles of supporting structures are explained. Two case studies of winter observations in areas controlled by supporting structures are presented. The take of supporting structures to prevent avalanches or to limit snow motion to a harmless magnitude is investigated by field studies. Examples of the interaction between moving snow and the structures are given. Then the main criterias for safety analysis are described and recommendations for the use of supporting structures are given.
