First trains through delft
24 May, 2016
The construction of a four-track railway tunnel in Delft in the Netherlands has reached an important milestone. From March 2015, trains have been running on two tracks through the tunnel and station. The 2.3km-long tunnel runs through the historical city center and replaces a fly-over, which caused major nuisance due to noise and vibrations. This article addresses a brief history and description of the project, some main design risks (safety, vibrations, pressure waves, building damage control), the geological and geohydrological conditions and the construction methods

Extreme Immersion Design
04 December, 2013
The Second Coen Tunnel must survive severe loadings during the usage phase: 16m of water in the middle of the North Sea Canal and 8m of soil at the banks. The determining design scenarios were the sea transport of two days and possible impact by a sunken ship. This article goes into the general immersed tube principle and the construction and transport phases. The usage phase will be covered in the next article, to be published in an upcoming issue of Tunnels
