Modelling glacial till under triaxial conditions using a BRICK soil model

The paper presents some findings from recent laboratory research aimed at improving ground-movement predictions in a hard, heavily overconsolidated lodgement till. These findings are subsequently applied to a new three-dimensional version of the BRICK soil model to investigate the suitability of this model for the till. It is shown that BRICK captures the essential features of the material's behaviour under triaxial conditions and is capable, when incorporated in a finite element code, of providing realistic predictions for the settlement of shallow foundations.Key words: glacial till, stiffness, strength, BRICK model, footing settlement.
