FUGRO COMPLETES FEHMARNBELT GEOTECHNICAL INVESTIGATION

摘要

Fugro has completed a nearshore geotechnical investigation for the FehmarTibelt Tunnel which is proposed to connect Denmark and Germany by road and rail and become the world's longest immersed tunnel.The company has been involved on the project for the past 10 years, from early site investigation work right up to the current geotechnical study. This latest phase included geotechnical site characterisation of the sub-seabed soil at both tunnel entrances and, on the Danish side, the production facility where the hollow concrete tunnel elements are being made.Fugro deployed its Skate 3 jack-up platform; a custom-designed geotechnical spread; and a specialist data-acquisition team to perform core drilling and downhole cone penetration tests. The resulting data were then analysed to determine the subsurface uncertainty to reduce the contractor's and the client's ground risk exposure by providing secured aeotechnical design input parameters.
