Soft ground tunneling - Ramboll Group

Ramboll has experience in all types of soft ground tunneling, on a range of projects for different purposes. One example is Ramboll's involvement in the design of a large diameter bored tunnel in the Nordhavn area of Copenhagen, where an important decision was the selection of either an earth pressure balance or slurry shield TBM.

Effects of tunneling on groundwater flow and swelling of ...

1. Introduction [2] Tunneling in clay‐sulfate rocks often faces substantial engineering problems because of the swelling behavior of such rock [Einstein, 1996; Anagnostou et al., 2010].The swelling manifests itself by heave of the tunnel floor, destruction of the lining, or even uplift of the entire tunnel and the ground surface above [e.g., Anagnostou, 1992].
