ABSTRACT
The contract T3 of the new Line C of the Rome underground is 2.8 km long and includes two stations and two ventilation shafts. It runs under the archaeological artefacts of the historical centre of Rome which is a UNESCO World Heritage site, an area with high density of monuments and historical buildings. Metro C, in cooperation with an interdisciplinary Scientific Technical Committee, has carried out several detailed studies to analyse the potential interactions of the monuments/historical buildings with the new line C, in order to identify the most appropriate and effective mitigation techniques to be adopted to prevent any damage. This paper describes the procedures that have been followed to safeguard the monuments/historical building interacting with the line during its construction, from the approach adopted to study the line-monument interaction at different levels of complexity, to the comparison between the computed and the observed displacement fields for the case of the Basilica di Massenzio.
