STRAIN BEHAVIOUR OF SOIL-FABRIC MODEL EMBANKMENTS
The paper considers the influence of placing horizontal and inclined multi-layers of non-woven melt-bonded fabric in plane strain model sand embankments 0.9 M high, 2.0 M half base width and 0.3 M thick, resting on a 0.3 M deep elastic foundation. From direct measurements of displacements in the model, direct and shear strains are calculated. Comparisons are made between the boundary displacements and internal embankment strains, with and without inclusions, for the two construction sequences used. The crucial importance of the construction sequence on the strain behaviours of the sand-alone embankments is identified and the influence of this on the effectiveness of the inclusions is highlighted. The applicability of the finite element method of analysis to the prediction of the behaviour of such soil-inclusion systems is suggested. (TRRL)
