Pressure-Settlement Characteristics of Strip Footing Resting on Randomly Distributed Fibre-Reinforced Sand Using Constitutive Law

Prediction of pressure-settlement characteristics becomes necessary for footing resting on improved ground with randomly distributed fibre-reinforced sand to work out its structural suitability and economic viability. The triaxial stress-strain curve simulates real behaviour of randomly disturbed fibre-reinforced soil (such as increased stresses with increasing strain, strain hardening, and ductile behaviour). Therefore, a constitutive law representing stress-strain curve would be suitable technique to predict pressure-settlement characteristics of footing resting on randomly disturbed fibre-reinforced sand (RDFS). In this paper, a method has been proposed to predict pressure-settlement characteristic of strip footing resting on RDFS using triaxial stress-strain curve on RDFS. Results have been validated through model footing tests conducted by authors and as reported in the literature.
