Abstract: New experiments are conducted on the French Cemagref full-scale experimental site in Lautaret Pass in order to improve knowledge about the action of a snow avalanche against structures. The main objectives are to provide realistic and general pressure distribution models usable for civilengineering design and to replace current restrictive hypotheses in this field. The experiment principle is original, based on the back analysis of structure’s behaviour and eventually damages: That means to quantify avalanche action from its consequences on realistic structures rather than from sensors placed directly in the flow. This approach is particularly useful for taking into account the mutual influence of flow and obstacle and for confirming that the result is truly the action experienced by the structure. This approach is also promising in that it ensures the coherence of the method with the tools usually used in mechanics or civil engineering design.
