Abstract

The aim of the paper is to analyse the influence of "micro-structure" and "meso-structure" on the stress-strain behaviour of two natural stiff clays in the pre-failure range. Results obtained by means of undrained cyclic and dynamic torsional shear tests on intact and “destructured” specimens of Vallericca clay and on remoulded and natural specimens of intensely fissured Bisaccia clay were compared. It has been found that for the natural specimens fabric and interparticle bond as well as the state of fissures noticeably affected shear modulus and damping ratio, either in the small and in the medium strain range.
