Behavior of Geosynthetic Reinforced Ring Footings Supported on Multilayered Soil Strata

Abstract This study is aimed at analyzing the behavior of ring footings on layered foundation systems. The influence of layer stratification, foundation type, and subgrade strength on the behavior of ring footings was studied. Various laboratory model experiments were performed for the ring and solid circular footings on homogenous and two-layered unreinforced and reinforced foundation systems. The layered system consisted of medium dense sand (DrT = 65%) of varying thickness (H = 0.66–2.66D) overlying the subgrade (lower layer) of varying relative density (DrB = 30%, 50%, 80%). The results show that the top layer thickness (H), subgrade relative density (DrB), foundation type, and the type of geosynthetic material utilized for reinforcement viz. geogrid, and geotextile considerably influences the performance of footings. As the top layer thickness and subgrade strength increased, the improvement factors for reinforced layered foundation systems decreased due to the lack of strain mobilization for the membrane action. The maximum contribution of the geosynthetic reinforcement to the bearing pressures was witnessed for the top layer thickness of H = 0.66D and loose subgrade system of DrB = 30%. The pressure settlement responses for all the cases indicate that the ring footing outperformed the circular footings and hence can be used as an effective and economical alternative to the conventional footings.
