ABSTRACT

Tunnelling in the urban environment has become a common activity as the demand for high-capacity public transport continuously increases, especially in big cities. This chapter presents a partly uncoupled procedure for the evaluation of tunnelling induced damage on historic buildings, focusing on Roman Renaissance masonry structures in particular. It also presents results of soil-structure interaction analyses carried out using the equivalent solid approach proposed by N. Losacco and addresses the applicability of the method to masonry buildings. Losacco et al. introduced an equivalent solid with the same geometry as the underground part of the examined building and with a transverse-isotropic, linearly elastic constitutive model. Soil-structure interaction is studied through finite element analyses using a simplified model of the examined building, called 'equivalent solid'. The equivalent solid model consists of the part of the building embedded in the soil and has a transverselyisotropic linear-elastic behaviour, with adequately calibrated moduli.
