Abstract
The tectonized clay shales of Souther Apennines are special materials which can neither be easily investigated and modelled with the usual criteria of Soil Mechanics, because of the presence of some weak bonding, nor with those of Rock Mechanics, due to very small and closely spaced random fissures. In addition, marked inhomogeneities may be significant even at the scale of laboratory specimens. Such peculiar features strongly influence the mechanical behaviour of these materials which are often a major problem for the design and construction of geotechnical works. The present reports, describes and discusses the behaviour of italian tectonized clay shales as foundation soils of large earthworks, in slope stability and in tunnelling problems. their behaviour is interpreted taking into account the role of fabric and structure, as well as of the physico-chemical environmental conditions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
