Abstract
A study of the effects of the construction of the C Line of Roma Underground on the Aurelian Wall has been carried out as a research project sponsored by the municipality of Roma through STA S.p.A. This paper summarises the results of the study for a section where the two closed-shield (10m in diameter) running tunnels pass directly beneath the Wall, with a skew of about 45 degrees. At first, ground movements induced from construction of the tunnels, for different positions of the excavation face, were estimated in greenfield conditions using empirical methods. In a second stage, three dimensional finite difference analyses were carried out to simulate the interaction between the Wall and the construction of the tunnels. A distinctive feature of the research was the extended investigation aimed at an adequate definition of a model of the subsoil and of the geometry and quality of the foundations of the Wall.Questo articolo è pubblicato sotto una Licenza Licenza Creative Commons
