Introduction to the competition
Finnish National Road Administration has organised a competition to calculate settlements at Haarajoki Test Embankment. The task is to calculate the settlements of the embankment constructed on clay ground, the lateral displacements and the pore water pressure changes in the soil. The Haarajoki test embankment was constructed during summer 1997 after the competition was closed. The embankment is constructed on clay ground in part without ground improvement an partly onto vertically drained area. The construction plan was given to the contestants in forehand, so the construction schedule and order were able to take into consideration in the calculations. The contestants were asked to make calculations using three unit weights and the proper answers were chosen after the measured unit weight. Measurements, which were done during the construction of the embankment, showed that the average unit weight of the embankment is 21 kN/m3.
You can look pictures at the test embankment site before the construction (picture 1 and picture 2) and picture about the test embankment (picture 3).
