A 700 metres long “cover and cut” tunnel has been constructed on highway 19 in Horten, a town 100 km south of Oslo. The tunnel is constructed in medium to soft marine clay using friction sheet piles. The clay is very sensitive and partly quick in the northern half of the tunnel. Steel sheet piles are serving as permanent tunnel supports. The sheet piles have no protection against corrosion and therefore have added thickness for long term load conditions.
