Aerodynamic Sizing of High Speed Train Tunnels – The Saverne Tunnel Case
Abstract: Aerodynamic sizing of a high-speed train tunnel is a critical design point as it conditions the choice of the tunnel cross section and therefore strongly impacts the project costs and planning. This article contributes to a better understanding of this subject by describing the aerodynamic studies and tests conducted for the Saverne tunnel (double tubes, 4 km long) lying on the LGV East High...

Management of construction time and cost effectiveness by imple mentation of the DAT software through the NeTTUN project
Abstract: The evaluation of the variability of the civil works duration and cost for the realisation of a tunnel is a determinant factor in choosing the optimal project planning and configuration alternative. The design, construction and operation of tunnels is associated with risks due to a lack of geotechnical information, the severity of a wrong construction choice, and the consequences that an...
