Test piles for Norwegian railway bridge

For the construction of a new railway bridge across Lake Mjøsa near Oslo in Norway, Aarsleff has carried out test driving of tubular steel piles and executed static load tests. At 836 metres, the new bridge will be the longest railway bridge in Norway. The purpose of our work was to determine the bearing capacity of the test piles, and the results were used to optimise the design of the foundations for the future railway bridge. We installed a total of eight piles, comprising two test piles and six reaction piles, all with a diameter of DN406.4 millimetres, a wall thickness of 12.5 millimetres and a length of 44 metres.
