STUDY ON REINFORCED EARTH RETAINING WALL WITH SUSTAINABLE BACKFILL

This study provided an insight into the potential of two sustainable materials for backfill.   Ø    The performance of copper slag and CDW was compared with that of the conventional material (sand) backfill application. To investigate the suitability of the materials, a finite- element analysis was carried out on MSE wall with plaxis-2D. Ø    The model RE wall and analysis will help in understanding failures before construction is taken up. The contribution of reinforcement in improving stability is significant. There is an improvement of 1.60 to 2.60 in factor of safety with reinforcement. Ø    The factor of safety of the RE wall found out using PLAXIS and generally the required factor of safety ranges between 1.3-1.5.
