Influence of Footing Interference on Bearing Capacity Improvement for Geogrid-Reinforced Sand Bed Underlain by Soft Clay
In the present paper, laboratory-scale experimental investigation has been carried out to study the effect of footing interference on bearing capacity improvement and settlement reduction of two closely spaced identical footings resting on unreinforced and geogrid-reinforced sand layer of limited thickness underlain by a soft clay layer. The effect of aspect ratio of footing on bearing capacity improvement and settlement reduction for interfering footings is also studied. At S/B=2 (where S is the spacing between the interfering footings), higher values of bearing capacity ratio (BCR), improvement factor (If), and settlement reduction factor (SRF) are observed for interfering footing compared to isolated footing. Further, it is observed that the magnitude of BCR, improvement factor, and settlement reduction factor decrease almost linearly with an increase in aspect ratio (L/B ratio) which indicates that BCR, If, and SRF decrease from square footing to strip footing.
