CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn the paper the first results of the geotechnical characterization of the volcanoclastic materials involved in the huge Dec. 30th 2002 landslides at the Stromboli volcano (Southern Italy) are reported. Firstly the physical characteristics of the aggregate and the petrographic, physical and mechanical characteristics of the grains are discussed. Successively, results of direct shear and oedometer compression tests on dry reconstituted specimens in a large direct shear apparatus are presented. Shear strength data are finally analysed on the basis of two non-linear strength criteria, usually adopted for coarse-grained materials.
