Abstract

An experimental investigation to analyse the anisotropic volumetric response of shaly and sandy facies of Opalinus Clay upon suction variations ispresented. Obtained results demonstrate the different behaviour of the tested facies to a wetting-drying cycle. The shaly facies exhibits higher water retentioncapacity and stronger volumetric response than the sandy facies. Anisotropic response is experienced by both facies with the strain perpendicular to beddinghigher than in the parallel direction. The sandy facies exhibits a more pronounced anisotropic behaviour in particular during the drying phase. A detailedanalysis of the response in the two directions with respect to the bedding orientation proves that the different anisotropic behaviour between the two facies ismainly caused by a different response parallel to bedding rather than perpendicular.
