LIGHT AT STOREBAELT TUNNEL END
A paper presented to the June 1995 meeting of the British Tunnelling Society in London is summarised. The fixed link between the islands of Funen and Zealand in Denmark comprises a combined motorway and railway west bridge and an east motorway bridge and separate railway tunnel. The two single lane tunnels, through subsoil in two distinct layers, glacial till and marl, are being constructed by slurry and earth pressure balance TBM. Glacial till contained boulders up to 3m in size and the chalk marl is highly fissured. Of the many problems encountered, the most significant was extreme wear due to the very abrasive nature of the glacial till. A chamber was constructed to examine and repair the cutterhead. High hydrostatic pressure of 5 bar was reduced to less than 3 bar. Tunnel flooding occurred during maintenance and a fire caused considerable damage to the TBM heading. The discussion following the presentation of the paper is also reported.
