Cityringen – Inner-city TBM tunneling in mixed face conditions
Abstract: Cityringen comprises twin TBM tunnels with a length of approximately 15,5 km connecting 17 new stations and 5 shafts through the old inner city of Copenhagen. The tunnelling in the Southern part of the ring is mainly driven through in Copenhagen limestone, whereas the Northern part of the ring includes mixed face and soft ground conditions. The tunnels are located at a depth of between 10 and...

COVID -19 acceleration planby change of TBM reception strategy
Abstract: With the fast spread of COVID 19 pandemic and the increased logistic difficulties, the Sydhavn Metro extension project in Copenhagen faced a significant risk of delay. To mitigate this delay, an acceleration program was agreed, which included a change of the TBM reception and launching strategy. The response to the pandemic crisis required fast decisions, prompt re-design and close proactive...

Evaluation of settlement parametersbased on TBM tunnellingin Copenhagen
Abstract: Prognosis on surface settlements above tunnels in urban areas are usually based on the empirical green field approach. The parameters necessary for estimating tunnel induced settlements are highly dependent on experiences with previous projects carried out with similar methods and under similar geological conditions. For the prediction of settlements of a new Stormwater tunnel in Copenhagen, a...

Mitigation works prior to soft ground tunnelling with low cover for the Copenhagen Cityringen Metro
Abstract: The Copenhagen Cityringen is currently under construction and due to expand the current Metro system by 17 new stations in 2019. The Cityringen crossing above the existing Metro tunnels at Kongens Nytorv in Copenhagen, Denmark necessitates shallow tunnelling in soft ground with EPB tunnel boring machines, beneath heritage buildings on shallow foundations in the historic centre of the city. The...
