Verifica della situazione delle pareti sovrastanti il tratto trentino della strada S.S.45 bis "Gardesana Occidentale Geoengineering assessment of rock slopes overhanging the Trentina dìstrict ofthe S.S.45 bis "Gardesana Occidentale

ln order to define the priority in new protection work of the Trentino district of S.S. 45bis "Gardesana Occidentale" a geoengineering study was performed allowed a better comprehensive hazard valuation. The geomechanical characterization carried out a geomorphological analysis, and defined homogeneous zones using index R.M.R. and G.S.I., localized the main unstable wedges, examined the possible kinematics movements and performed a comprehensive rockfall analysis, attained an hazard assessment of the area. The engineering characterization of protection works defined special schedules to evaluate the efficiency and effectiveness of the existing one: rock shed, tunnels, rockfall barriers and draped meshes in order to decide upon the priority of new protection works.
