Drill and Blast Vibration Monitoring: Overpass of A10 Motorway
Abstract: Drill and blast excavation produces the propagation of seismic waves with consequent vibration phenomena in the surrounding rock mass, interfering with pre-existing structures or infrastructures. The paper presents the case of Borzoli Erzelli Tunnel (excavation area equal to 120m). The tunnel has to overpass two tubes of existing motorway tunnel “Don Guanella” in operation with only 6m gap. In...

Earth Pressure Balance (EPB) TBM excavation the case of Serravalle tunnel (Terzo
Abstract: Earth Pressure Balance (EPB) TBMs are able to deal with the main issues in urban tunnelling that include surface settlement control, maintaining of the existing structures requirements and stability of the excavation face. Tunnels of several kilometres can also include quite different conditions along the tunnel alignment in terms of rock / soil characteristics, groundwater and overburden. In...

High Speed Railway Milan – Genoa, Parametric analysis of rock stress-strain control during tunnel excavation in the...
Abstract: The Stretch of the Italian high speed railway between Milan and Genoa is currently under construction and will be completed by 2021 with more than 85 km of tunnels. More than 60 % of the tunnel excavation will be realized in the “Argille a Palombini” formation (aP), characterized by an alternation of claystone schists with limestone lenses, highly tectonized and squeezing. The paper describes...

High-Speed Railway Milan – Genoa, implementation of coupled analysis to estimate thermo-mechanical effects produced...
Abstract: The Stretch of the Italian High Speed Railway between Genoa and Milano is currently under construction with more than 78 km running tunnels and will be completed by 2021. More than 20 km of the tunnel excavation will be executed by EPB TBM, with overburden ranging from 5 to 600 m and geomechanical condition varying from hard rock to soft marble. Segmental lining, in precast concrete and...

Naturally occurring asbestos in the Rocks belonging to Sestri – Voltaggio Zone (Liguria, Northern Italy). Excavation...
Abstract: The project and construction for the new high speed railway line (connecting Genoa to Milan) faced one of the most important environmental issues: safe excavation and managing of rocks, that may contain asbestos in relevant amounts. Asbestos is a group of fibrous minerals that mainly occurs in mafic and ultramafic rocks (ophiolitic sequences). This work focuses the criteria to better evaluate...
