HORIZONTALLY REINFORCED FILLINGS ON SOFT SUBSOIL

HORISONTALARMERADE FYLLNINGAR PAA LOES JORD

The purpose of this project has been to find out if fabrics for stabilizing soil have any effect at all and to find out how fabrics work under an embankment. The test has been performed on a model of an embankment on soft clay, with different numbers of fabric layers at the base of the embankment. The scale used for the model test was 1:20 for the shear strength of the model subsoil materials. The tests were carried out in a box of plexiglass. During the tests, the bank was built up step by step until failure occurred in the subsoil. A photograph was taken between every step in the construction of the embankment. The results show that fabrics at the base of an embankment reduced the horizontal deformation at the embankment base. The effect on the vertical deformation is more re-distributive, which means that the vertical deformation under the middle of the bank decreased while those under the slope increased. The effect of the fabrics was greater on low embankments and for an increasing width at a given height. The fabric shall have a modulus in tension so that at an extension corresponding to failure in the subsoil (about 1.5% for clay) will mobilize a force corresponding to the maximum active earth pressure in the embankment.
