Aim: The aim of the present study is to analyse the effects of different backfill types on the bearing capacity of a square footing located on wrap-around geosynthetic reinforced soil (GRS) retaining wall. Materials and Methods: Geosyntheitc reinforced soil retaining wall models are prepared in a transparent container. Square footing is placed on a retaining wall and subjected to compressive load in a loading frame. (Group 1: GRS retaining wall with sea sand backfill, N = 17. Group 2: GRS retaining wall with M-sand backfill, N = 17). Pre-test power and confidence intervals were chosen as 80% and 95% respectively for sample size calculation. Result: Test results show that GRS retaining wall with 4 cm reinforcement spacing performs better than a GRS retaining wall 6 cm spacing. There is a significant difference (2 tailed) between two groups of GRS retaining wall as the value of p is 0.008 (p<0.05) for cohesion in statistical analysis. Conclusion: Closer reinforcement spacing increases the bearing capacity of square footings.
