Abstract

In the present time, waste tyres are increasingly being used in many geotechnical applications like embankment fill, retaining wall, machine foundation, bridge abutment etc. From the previous studies, it had been noted that the tyre chips mixed with soil are used as a backfill material for earth-retaining structures. In the present study, a numerical simulation using OPTUM G2 (finite element based numerical tool) has been adopted to evaluate the effect of waste tyre as a backfill material on total lateral earth pressure for an 8 m high wall. In all the cases, wall backfilled with waste tyres are found to be safer than the wall backfilled with soil. From this study, it has been found that mixing of waste tyre as a backfill material substantially reduces the total earth pressure on the wall in the range of 50-54% as compared to wall backfilled with the soil.
