A new experimental snow avalanche test site at Seehore peak in Aosta Valley (NW Italian Alps) — Part II: Engineering aspects
Abstract The estimate of the effects produced by the impact of a snow avalanche against an obstacle is of the utmost importance in designing safe mountain constructions. For this purpose, an ad-hoc instrumented obstacle was designed and built in order to measure impact forces of small and medium snow avalanches at Seehore peak (NW Italian Alps). The structural design had to consider several specific and unusual demands dictated by the difficult environment. In this article, the new test facility is described from the engineering point of view, discussing the most important aspects of the analyzed problems which were solved before and after the construction. The performance of the instrumented obstacle in the first two operating seasons, and some proposals for future upgrading are eventually illustrated.
Highlights ► Setup of a new site for testing the effects of the impact of snow avalanches on the constructions ► Conception of a system of sensors capable to measure the pressure generated during the impact of avalanches ► Remote continuous recording of natural and artificially triggered avalanches
