摘要：Non availability of suitable construction site due to rapid growth of population requires use of lowlaying areas. Low laying area can be used by suitable structural fill. Well compacted granular fill materials arecommonly used to fill the low laying areas. Sometimes, it is required to strengthen the granular fill with some suitablereinforcing materials to increase its bearing capacity. Vertical spacing between reinforcement layers is one of theimportant geometric parameters which affect the response of the footing resting on granular fill material. In the presentstudy granulated blast furnace slag (GBFS) has been used as granular fill and response of circular footing has beenevaluated by varying the vertical spacing of geogrid reinforcement. Response of circular footing obtained in terms ofincrease in bearing capacity and decrease in the settlement. Vertical spacing of 0.3D has been obtained as optimum andoptimum spacing of geogrid reinforcement increases the bearing capacity by 95% and decreases the settlement by 48%as compared to footing resting on unreinforced GBFS bed. Experimental test results were compared with numericalsimulation and found reasonable match with experimental results.
