Centrifuge Tests on Methods Stabilizing Embankments
A test programme has been carried out in the geotechnical centrifuge of the University of Delft to investigate how different design parameters influence the failure mechanisms and displacements of dikes stabilized by three innovative methods. The three methods under investigation are known as: mixed in place, soil nailing and expanding columns. The tests included models without reinforcements (9 tests) as well as models partly simulating mixed in place (6 tests), soil nailing (6 tests) and expanding columns (5 tests). Some of these tests are discussed in this paper. The parameters tested were expected to have a significant influence on the three innovative methods. Centrifuge research indicates that, in comparison with non-reinforced models, all three innovative methods can improve stability. The extent of the improvement depends heavily on the design parameters, such as the smoothness, the number, the inclination and the stiffness of the reinforcing structural devices. It was possible to adjust the design of all three methods so that the model did not fail.
