Abstract: Along the track of Thessaloniki Metro, the two precast segment lining tunnels pass through an active fault named “Philaya”. According to the available data from scientific bibliography, (most important: Pitilakis and associates, 2014 expertise report), the fault plane is assumed to cross the longitudinal tunnel axis perpendicularly, under a dip angle of 60° or 70°. The potential coseismic...
Abstract: the central stretch of the Warsaw Metro Line 2 has an extension of 6,3 km with 7 stations. The paper describes the underpass of Vistula River which has been the most critical of several significant underpasses dealt during the excavation with the TBM. The collected geotechnical data and bathymetric surveys have been useful to define the TBM parameters according the A.DE.CO-RS design approach....
