ADECO and NATM comparison: the case of Višňové Tunnel
Abstract: The paper presents the application of the “A.DE.CO-RS Approach” for the construction of “Višňové Tunnel” in D1 Motorway. It is a double lane tunnel of the D1 Motorway “Lietavská Lúčka – Višňové – Dubná Skala”, about 7450 m length. It’s located in the Žilina district of Slovakia. In a Yellow FIDIC contract, the JV Salini Impregilo–DUHA proposed to the Client a variation of the excavation...

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...

Haga Station and Quick Clay of the West Link Project in Gothenburg - Geotechnical
Abstract: Haga Station is part of the West Link Project in Gothenburg, which is one of Sweden’s largest and most complex rail projects. Part of the station is located in glaciomarine clays deposits with an estimated depth of 45-50 m, covered by filling consisting of gravel and sand with a thickness between 1 and 5 m and separated from the bedrock by a friction soil layer with thickness ranging between...

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...

Industrialisation of the construction process for the Solbiate Olona tunnel by using “jet-grouting” technology
Abstract: The Solbiate Olona tunnel represents a very significant project, solving the problem of interference between the “Pedemontana Lombarda” Motorway alignment and one part of the Solbiate built area, overlooking the Olona Valley. After a long stretch of cut & cover tunnel, the tunnel passes underground through gravelly-sandy ground, beneath various residential...

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...

Passage of a precast segment lining tunnel through an active fault - Special segments and details – Thessaloniki metro
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...

Planning of Tunnels in landslides situation: the experience in the Italian Apennines
Abstract: In the planning of underground structure, geological, geomorfhological and hydrogeological aspects have to be carefully investigated in order to evaluate risk assessment between the new excavation works and the pre-existing, especially in the presence of landslides. In this paper, a methodology approach is presented, considering some recent experiences in the Italian Apennines collected on...

Seismic site response a comparative study considering Italian standard code
Abstract: Italy is one of the countries in the Mediterranean with the highest seismic risk. The Italian technical standards for construction since 2008 requires the estimation of seismic site amplification. The paper attempts to give a critical overview of the field of site response analysis evaluating the influences of the main sources of uncertainties considering Equivalent Linear and Non Linear...

The application of Semi-Automatic Tubular Arch inside Boscaccio Tunnel: a new concept of primary lining
Abstract: Tunnel excavation is a particularly hazardous activity due to working in confined spaces, in addition uncertain ground conditions and the use of heavy equipment creates additional occupational safety and health hazards for site personnel. One of the most important request of underground construction market is a safety level increase during excavation stage. The risks are well known and this...

The reinforcement of the core-face: history and state of the art of the Italian technology that has revolutionized...
Abstract: Systematic reinforcement of the core-face of a tunnel using glass-fiber elements as a structural component to stabilize it in the long and short term is a practice developed in ltaly that has been used for over twenty-five years. During this period significant developments for core-face reinforcement technique have occurred in design approach, construction technologies and materials. This paper...

The role of underground transportation inside Milano’s Smart City perspective
Abstract: Making a Smart City out of a city is a complex process involving deep-rooted innovation with regard to: tangible and intangible infrastructures, the lifestyles of citizens; the regeneration and design of public spaces, strategies and tools to develop the economy and the handling of complexities. Public administration on its own cannot transform a city into a smart city, but it does have the...

Warsaw metro Line 2: TBM Excavation in difficult condition: The underpass of Vistula river
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....
