Bearing Capacity of Strip Footing Rest on Reinforced Industrial Slags and Silty Clay Beneath

Abstract

This study was done to investigate the bearing capacities of strip footing on reinforced and unreinforced copper slag and induction furnace slag overlay compacted silty clay (i.e. double layer system) and their effectiveness using model tank tests in laboratory. Various parameters are investigated such as H/B (thickness of top layer to width of footing), u/B (location of the first layer of reinforcement to the width of footing), h/B (vertical spacing between consecutive geogrid layers to width of footing), b/B (length of the geogrid layer to the width of footing). The effect of H/B ratios and geogrid reinforcement N values on BCR (bearing Capacity ratio) and SRR (settlement reduction ratio) were also investigated. The results show that there is significant increase in the bearing capacity with increasing H/B ratio as well as the no. of geogrid layers.
