Po River Project, Italy

A new high speed railway line from Genoa to Milan required interconnecting the new infrastructure with the Giovi, Genoa - La Spezia, Genoa-Turin and Alessandria-Piacenza lines, and involving the interports of Rivalta Scrivia and Milan South. This involved the construction of several new high speed railway lines taking trains at speeds of 300km/h. As part of this project, Piacenza became the site for the first Osterberg Cell tests to be performed in Italy.

Two multi-level O-cell® tests were performed on 2000 mm piles installed by Trevi Spa. The piles were constructed using bentonite slurry to depths of 52.3 and 57.7 metres.

By placing the O-cell® at strategic elevations in the shaft, Loadtest was able to assess shear characteristics in specific zones, as well as isolate end bearing and total skin friction loads. These tests provided evidence of the technical merits of O-cell® technology and the benefit the method can have by minimising disruption to the environment.
