| Abstract: |
To counteract the high volume of traffic in the historical city of Karlsruhe, Germany, the rail infrastructure of the above-ground tracks is being moved underground while maintaining full pedestrian, road and tram operation. To this end, seven underground stations will be built in the cut-and-cover / dig-and-cast design, and subsequently connected by a tunnel boring machine (TBM) before excavation. After the preparation of the tunnel, the underground stations shall be excavated via the newly established tunnel tube. The concrete construction of the stations will then be a waterproof construction. The challenge of this downtown project is designing the construction for the handling of the historical buildings in relation to settling and in the construction logistics, involving the step-by- step manufacture of the covers while keeping the traffic above ground running. |
