Abstract:

This work aims to verify the influence of the Rio Pontè, a tributary of the Dora Riparia river, on the current integrity of the structures constituting the Serre la Voute A32 viaduct, located in the municipality of Salbertrand (Torino) by virtue of the presumptions on instability and erosion phenomena due to the sediment transport and the fluvial dynamics of the river. The behavior of the so mentioned waterway will be analyzed with particular attention to the hydraulic behavior and the dynamics of solid transport. Particularly, it is intended to determine the erosion in the riverbed, specifically in correspondence with the structures of interest, whose integrity can be influenced by the fluvial dynamics, these structures correspond to two pillars, and two abutments built in reinforced concrete and footing on micro-piles of variable length, determined by the depth of the rigid and compact substrate. A Hydraulic and Sediment Transport model will be built to be implemented with the HEC-RAS numerical software which is worldwide use in the engineering field. The results obtained will be analyzed to evaluate the need for implementation of works aimed at reducing hydrogeological risk and consolidation of the slopes corresponding to critical areas, such as the implementation of geosynthetics for erosion control and rockfall barriers for the protection of the viaduct structures.
