This paper examines the effects of suction and compaction-induced fabric on mechanical behaviour of soils. The discussion mainly focuses on: (a) the transition form saturated to unsaturated state, (b) the behaviour in the small strain range and (c) the effect of moulding water content on compacted soils' mechanical response. Laboratory tests were conducted at the Dipartimento di Ingegneria Geotecnica (DIG) of Naples on unsaturated silty sand compacted at the optimum and wet of optimum water contents. The experimental program carried out on this material included both triaxial and resonant column - torsional shear tests, all conducted under controlled suction conditions.

Abstract
This paper examines the effects of suction and compaction-induced fabric on mechanical behaviour of soils. The discussion mainly focuses on: (a) the transition form saturated to unsaturated state, (b) the behaviour in the small strain range and (c) the effect of moulding water content on compacted soils' mechanical response. Laboratory tests were conducted at the Dipartimento di Ingegneria Geotecnica (DIG) of Naples on unsaturated silty sand compacted at the optimum and wet of optimum water contents. The experimental program carried out on this material included both triaxial and resonant column - torsional shear tests, all conducted under controlled suction conditions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
