Abstract

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.
