Abstract

Isotropically consolidated-drained triaxial compression tests were performed on undisturbed structured/cemented silt to gain a better understanding of the shear behavior of and hyperbolic stress-strain parameters for this material. The results show that the hyperbolic stress-strain parameters for the structured/cemented silt are anisotropic and differ significantly from the hyperbolic parameters developed for silt reconstituted at the field total unit weight and water. As the confining pressure in a triaxial compression test approaches the preconsolidation pressure, the effects of the structure/cementation are reduced due to bond breakage, and the structured/cemented silt exhibits a stress-strain behavior similar to that of reconstituted silt.
