Abstract
This paper presents experimental research concerning the shear behavior of two types of Italian peat, one normally, the other over consolidated. Organic soils are characterized by very high compressibility and high fiber content; two features that give rise to several problems during laboratory tests. Under consideration here are the effects of fibers and over consolidation on friction angle and stress–strain behavior. These are evaluated by means of undrained compression triaxial tests, with isotropic and anisotropic (
