THE IMPORTANCE OF DEFINING THE GEOMETRY OF FOUNDATIONS AND SOIL LAYERS FOR DYNAMIC ANALYSIS OF COLOSSEUM

By the comparison between tests and analyses, the dynamic characterization was performed, in order to obtain the map of elasticity modules for soil Colosseum interaction. The accuracy for foundations and soil is lower than for monument, due to unknown exact geometry underground. For foundations, a high variability was found of elasticity modules, which was referred to variable damage of concrete for cracking in time. For soil layers, different definitions exist, and we are interested in the best. The vibrations produced by trains are depending on the underground geometry too. The analyses are performed with traditional convoys running on Metro B and C, for the vibrations knowledge on RA XLVII and on ground felt by pedestrians.
