Soft ground tunneling

A wide variety of techniques are available for soft ground tunnelling, ranging from Tunnel Boring Machines (TBMs) with segmental linings to Sprayed concrete linings (SCL – also known as the New Austrian Tunnelling Method, NATM). 
 
 
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.
 
Many soft ground tunnels are located in sensitive urban environments, where settlement due to tunnelling is a major concern. We have experience on impact assessment studies for projects such as Crossrail in London.
 
Tunnels come in all shapes and sizes, so at the other end of that spectrum we are involved in the microtunnelling project at Hvidovre in Denmark. No matter how large or small the project, we understand its unique importance to the client.
