This paper presents the analysis results of Colosseum area structural vibration phenomena due to the metro train transits considering also those due to the imminent opening of further underlining line, perpendicularly crossing to the already existing one. The dynamic soil-structure interaction connected to rail traffic is studied by using 3D models of soil-structures and trains functionally connected and both refined with experimental data. The archaeological study area of Rome is accurately reproduced by a finite element model including the monument structures and its disconnections, the soil layers and rail infrastructures. The transit combinations of real trains are modelled by a rigid body analysis method according the tested motion parameters. The results of analyses due to a severe train transits combination are presented and discussed for one Colosseum structure section.
