STABILITY OF SLOPES CONSTRUCTED WITH POLYESTER REINFORCING FABRIC

This report describes a practical test conducted with a view to finding out whether a horizontal fabric mat installed in an embankment can favourably affect the stability thereof. The problem is stated and the arrangement of the experimental section and its equipment is explained. The development of the strain gauge measuring technique for this research is described. The results of visual observations, measurement and calculations are then presented, from which it emerges that the contribution that a reinforcing mat makes to stability is indeed appreciable. Failure of a reinforced sand fill occurred when it had been raised to a height of 3 M above original ground level, whereas the corresponding height for an unreinforced fill was 1.75 M. The calculations based on the results - involving the analysis of horizontal equilibrium and the equilibrium of a circular surface of sliding - showed the order of magnitude of the force required in the reinforcing fabric to be 100 kn/m, which was in good agreement with the values calculated from the measured maximum strains.
