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.

Projects

Nordhavnsvej – the largest road construction project in Copenhagen in 50 years

The project for “Nordhavnsvej” is the first stage of a new road to Copenhagen’s Nordhavn (North Harbour). Nordhavn is an old industrial and port area, planned to be developed into a new urban area in the north-eastern part of Copenhagen. When fully developed, the urban area is planned for 40,000 residents and 40,000 workplaces.

Tunnel under Marselis Boulevard

The project consists of a 1.8 kilometre cut and cover tunnel, consisting of mechanical and electrical installations, several road and railway bridges (including railway bridges at Langenæs, Åhavevej and Viby Ringgade), and all temporary structures.

Orientkaj Station will be one of the new metro stations in Nordhavnen

Nordhavn Metro Extension

Ramboll, in a joint venture with Arup and with architectural firm COBE as sub-consultant, is the planning advisor for the Nordhavnen Metro extension in central Copenhagen.
