Project Description
The High Speed Railway Project is a great example of a major extensive infrastructural project, which includes a significant set of complex and integrated activities. The Milan-Bologna high-speed railway is a link in the Italian High-Speed/High Capacity rail network. One of the main reasons for the complexity of this Railway Project was the track positioning in a relatively densely populated area along the Milan-Bologna highway.
This required: relocation of vital public services, such a schools, buildings, etc..
Re-stitching and rearranging the connection of many transversal roads, including the repositioning of certain sections of the 200 km long Milan-Bologna 6 lanes motorway, since the motorway is adjacent to the railtrack for 75% of its length.
The cable stayed bridge over the Po river
The new Bologna Milano High Speed/High Capacity railway line crosses the river Po one kilometre after Piacenza, where the ordinary riverbed is 350mt wide and the distance between the main embankments is more than 1km. The 22° angle between the crossing and the river meant the construction of a 1.2km long bridge, with 400mt necessary to cross the riverbed. The need to meet navigability and environmental requirements brought to the choice of a cable stayed bridge with 192mt long main span that, once in service will be one of the longest in the world for High Speed railways.
In fact, it is designed to permit the safe passage of trains at high speed also more than at 300 km/h while the other cable-stayed bridges support a speeds up to 250 km/h only.
The viaduct across the Po river is a system crossing Italy’s largest river, connecting the two regions of Lombardia and Emilia Romagna :
Full viaduct extension of around 1,350 m.
The cable stayed viaduct, 400 m long, with central bay and lateral bays, respectively of 192 m and 104 m, with foundations on 2 artificial islands.
The bridge, built with pre-stressed reinforced concrete, sustained with 72 stays connected to two towers 60 m above the foundations.
The towers foundations designed to resist to heavy erosion, each one built on 28 piles 2 m wide and 65 m long.
