MECHANICAL EFFECTS ON INTERSTITIAL WATER--DETERMINATION OF COMPLEX MODULI OF LONGITUDINAL DEFORMATION AND SOIL SHEAR AS A FUNCTION OF SUCTION

EFFETS MECANIQUES DE L'EAU INTERSTITIELLE||DETERMINATION DES MODULES COMPLEXES DE DEFORMATION LONGITUDINALE ET DE CISAILLEMENT DES SOLS EN FONCTION DE LA SUCCION

The object of this research is to determine, for the various cohesive soils representative of road subgrade soils, the physical variables which play a part in practical rational design methods for roads, taking into account the humicity--characterized by suction values--and the degree of compaction of these soils as well as the static stresses which arise from the weight of the road structure. In order to determine these physical variables the resonance method is used. This consists of subjecting one end of a cylindrical sample of the soil, of a known length and bulk density, to sustained sinusoidal (longitudinal or torsional) vibrations of increasing frequency, and to measure the resonant frequency.
