Ground conditions in the Fehmarnbelt

No obstacles to construction
Investigations so far have shown that there are no geological or geotechnical reasons that preclude the building of a Fehmarnbelt Fixed Link. The geotechnical conditions in the Fehmarnbelt may be highly complex, but consist of known strata. This was the conclusion of the geotechnical investigation report published in May 2011.

Glacial influences
The results of the investigations largely correspond to what was expected, based on the preliminary studies of the 90s. However, it has become apparent that the layers of clay in the near-shore areas were more heavily influenced by the ice-age glaciers than previously thought.

This so-called Palaeogene clay layer on the Danish coastline is at such a depth that it will not be affected by the coming construction work. But off the German coast, excavation work will have to be done in this layer as it lies close beneath the seabed. Extensive underwater testing are being out there at a special test site to measure and monitor movement in the soil under different load conditions.

The knowledge of the geotechnical conditions in the Fehmarnbelt is so detailed that interested construction companies have already gained a preliminary impression of the ground conditions and can make their preparations for the tendering process.
