摘要: Abstract Induced anisotropy can be applied to soils in different ways, natural or laboratory conditions. The aim of this work was study the effect load compaction a specific remoulded residual soil from granite, especially terms its on critical state behaviour and isotropic compression. For that purpose, compression tests triaxial were performed up high pressures specimens compacted two ways: by moist tamping multi-layer heavy static imposed frame. results indicated consolidation minimize compaction, although anisotropic still remains expressed normal lines for each type despite lack particle crushing. same observed when obtained taken strains. Analysis radial axial strains as well velocities shear waves transmitted polarised under distinct paths directions also clear showing pattern stress–strain behaviour.
